The autoexpect script in Expect's example directory does what you want.

Sending control characters is easy: just write a send command and enter the control character you want to send.

I like to enter most control characters literally - since the resulting script is more readable. However, your editor has to allow this. For example, suppose you want to send a Control-A. Conventionally, most editors display this as ^A, but you can't just enter ^ and A. (This will just send those two characters.) Most editors have some simple quoting mechanism that lets you enter the next character literally. For example, using emacs, I can enter ^Q^A and that will add the single character ^A.

Alternatively, Tcl provides a way of encoding using octal or hex. The octal encoding mechanism is less error-prone than hex so I'll demonstrate using octal. For example, since ^A has the octal value 1 in ASCII, to send a ^A:

    send "\01"

To send function keys, you need to know one more thing - what characters are assigned to a function key. Function keys are generally specific to the type of terminal (or terminal emulator) you are using, so it's easiest to just try pressing the function key and see what you get. In order to get the clearest picture, I use the od program to help me. Here are the steps I use:

1. start od with the -c option
2. press the function key
3. press the return key
4. press ^D

Here's what it looks like when I do that to find out what my F1 key generates:

    % od -c
^[[11~
0000000 033   [   1   1   ~  \n
0000006
%

The string between the 0000000 and \n is what we want. You can translate that into a send command like this one:

    send "\033\[11~"

Notice that the 033 was an octal specification already so I put a backslash in front of it to tell Tcl to treat it that way. I also put a backslash in front of the [ to prevent Tcl from trying to execute the next thing as a command.

One complication: characters may massaged (stolen or replaced with other characters) by the terminal driver. For example, in the example above, all the characters produced by the function key were sent to od, but the return character I pressed afterward was translated to a newline - which showed up as in the output of od). Unfortunately, there is no trivial way of turning off all such processing, but you can get rid of the usual offenders by executing the command:

    stty -isig -icanon -exten -ixon -ixoff

This will take care of most driver translations - except for return to newline which you probably don't want to mess with. Since ^D will stop working, you'll need to enter enough characters to get od to finish a line. Enter at least 15 more characters and press return to see some output from od.

Most systems support "stty raw" as a shortcut for the stty command above however not all do. In fact, some systems may not support all the options above. You may have to do some experimentation. Also note that some shells automatically undo any stty command that they "don't like". For example, the Z-shell (zsh) requires "ttyctl -u" before doing a stty like the ones above.

Hopefully, this should answer most of the questions. If you have further questions, please check the book. It has lots of examples of common literal, octal and hex sequences, and using these with send. Plus, it also talks about more sophisticated issues such as using function keys with termcap/terminfo.

Problem-solving is not a science, but part art and part skill. It is one of the skills most worth developing.
解题不是一门科学，而是一种技艺，是最应该培养的技艺之一。这里所说的问题可以是学习、工作、生活中的任意问题，按照数学大师波利亚的“如何解题”的思路，遇到问题时我们的思路就不至于freeze up，而是有章可循！

Summary taken from G.Polya' book "How to Solve It"

1. UNDERSTANDING THE PROBLEM
   • First. You have to understand the problem.
   • What is the unknown? What are the data? What is the condition?
   • Is it possible to satisfy the condition? Is the condition sufficient to determine the unknown? Or is it insufficient? Or redundant? Or contradictory?
   • Draw a figure. Introduce suitable notation.
   • Separate the various parts of the condition. Can you write them down?
2. DEVISING A PLAN
   • Second. Find the connection between the data and the unknown. You may be obliged to consider auxiliary problems if an immediate connection cannot be found. You should obtain eventually a plan of the solution.
   • Have you seen it before? Or have you seen the same problem in a slightly different form?
   • Do you know a related problem? Do you know a theorem that could be useful?
   • Look at the unknown! And try to think of a familiar problem having the same or a similar unknown.
   • Here is a problem related to yours and solved before. Could you use it? Could you use its result? Could you use its method? Should you introduce some auxiliary element in order to make its use possible?
   • Could you restate the problem? Could you restate it still differently? Go back to definitions.
   • If you cannot solve the proposed problem try to solve first some related problem. Could you imagine a more accessible related problem? A more general problem? A more special problem? An analogous problem? Could you solve a part of the problem? Keep only a part of the condition, drop the other part; how far is the unknown then determined, how can it vary? Could you derive something useful from the data? Could you think of other data appropriate to determine the unknown? Could you change the unknown or data, or both if necessary, so that the new unknown and the new data are nearer to each other?
   • Did you use all the data? Did you use the whole condition? Have you taken into account all essential notions involved in the problem?
3. CARRYING OUT THE PLAN
   • Third. Carry out your plan.
   • Carrying out your plan of the solution, check each step. Can you see clearly that the step is correct? Can you prove that it is correct?
4. Looking Back
   • Fourth. Examine the solution obtained.
   • Can you check the result? Can you check the argument?
   • Can you derive the solution differently? Can you see it at a glance?
   • Can you use the result, or the method, for some other problem?

读书笔记：
1. 编译器需要知道源语言的形式化定义，即由有穷规则描述的形式化的语法，这样才能在语法空间里派生出一个句子原型，然后把该原型与输入句子的抽象描述进行匹配。如果完全匹配，则说明输入的句子确实是目标语言的一个句子，也即语言空间里的一个元素。
2. 对于计算机编程语言来说，把输入的指令句子，如 int x=3; 分割成符号流 int x = 3 ; 然后抽象成语法变量描述：keyword id operator number ;  然后再在语言的文法空间里查找是否有可以派生出一条句子原型与这个抽象描述匹配。

3. at this point  在这一点上
   Could I put in a word at this point? 我现在说几句行吗？
   At this point, your logic is at fault. 在这一点上你的推理是错误的。

5. fit into  vt. 适应、符合

If you are one of those executive types unhappy at your present post and embarking on a New Year's resolution to find a new one, here's a helping hand. The job interview is considered to be the most critical aspect of every expedition that brings you face-to- face with the future boss. One must prepare for it with the same tenacity and quickness as one does for a fencing tournament or a chess match.

1. Tell me about yourself.

Since this is often the opening question in an interview, be extracareful that you don't run off at the mouth. Keep your answer to a minute or two at most. Cover four topics: early years, education, work history, and recent career experience. Emphasize this last subject. Remember that this is likely to be a warm-up question. Don't waste your best points on it.

2. What do you know about our organization?

You should be able to discuss products or services, revenues, reputation, image, goals, problems, management style, people, history and philosophy. But don't act as if you know everything about the place. Let your answer show that you have taken the time to do some research, but don't overwhelm the interviewer, and make it clear that you wish to learn more.

You might start your answer in this manner: "In my job search, I've investigated a number of companies.

Yours is one of the few that interests me, for these reasons..."

Give your answer a positive tone. Don't say, "Well, everyone tells me that you're in all sorts of trouble, and that's why I'm here", even if that is why you're there.

3. Why do you want to work for us?

The deadliest answer you can give is "Because I like people." What else would you like-animals?

Here, and throughout the interview, a good answer comes from having done your homework so that you can speak in terms of the company's needs. You might say that your research has shown that the company is doing things you would like to be involved with, and that it's doing them in ways that greatly interest you. For example, if the organization is known for strong management, your answer should mention that fact and show that you would like to be a part of that team. If the company places a great deal of emphasis on research and development, emphasize the fact that you want to create new things and that you know this is a place in which such activity is encouraged. If the organization stresses financial controls, your answer should mention a reverence for numbers.

If you feel that you have to concoct an answer to this question - if, for example, the company stresses research, and you feel that you should mention it even though it really doesn't interest you- then you probably should not be taking that interview, because you probably shouldn't be considering a job with that organization.

Your homework should include learning enough about the company to avoid approaching places where you wouldn't be able -or wouldn't want- to function. Since most of us are poor liars, it's difficult to con anyone in an interview. But even if you should succeed at it, your prize is a job you don't really want.

4. What can you do for us that someone else can't?

Here you have every right, and perhaps an obligation, to toot your own horn and be a bit egotistical. Talk about your record of getting things done, and mention specifics from your resume or list of career accomplishments. Say that your skills and interests, combined with this history of getting results, make you valuable. Mention your ability to set priorities, identify problems, and use your experience and energy to solve them.

5. What do you find most attractive about this position? What seems least attractive about it?

List three or four attractive factors of the job, and mention a single, minor, unattractive item.

6. Why should we hire you?

Create your answer by thinking in terms of your ability, your experience, and your energy. (See question 4.)

7. What do you look for in a job?

Keep your answer oriented to opportunities at this organization. Talk about your desire to perform and be recognized for your contributions. Make your answer oriented toward opportunity rather than personal security.

8. Please give me your defintion of [the position for which you are being interviewed].

Keep your answer brief and taskoriented. Think in in terms of responsibilities and accountability. Make sure that you really do understand what the position involves before you attempt an answer. If you are not certain. ask the interviewer; he or she may answer the question for you.

9. How long would it take you to make a meaningful contribution to our firm?

Be realistic. Say that, while you would expect to meet pressing demands and pull your own weight from the first day, it might take six months to a year before you could expect to know the organization and its needs well enough to make a major contribution.

10. How long would you stay with us?

Say that you are interested in a career with the organization, but admit that you would have to continue to feel challenged to remain with any organization. Think in terms of, "As long as we both feel achievement-oriented."

11. Your resume suggests that you may be over-qualified or too experienced for this position. What's Your opinion?

Emphasize your interest in establishing a long-term association with the organization, and say that you assume that if you perform well in his job, new opportunities will open up for you. Mention that a strong company needs a strong staff. Observe that experienced executives are always at a premium. Suggest that since you are so wellqualified, the employer will get a fast return on his investment. Say that a growing, energetic company can never have too much talent.

12. What is your management style?

You should know enough about the company's style to know that your management style will complement it. Possible styles include: task oriented (I'll enjoy problem-solving identifying what's wrong, choosing a solution and implementing it"), results-oriented ("Every management decision I make is determined by how it will affect the bottom line"), or even paternalistic ("I'm committed to taking care of my subordinates and pointing them in the right direction").

A participative style is currently quite popular: an open-door method of managing in which you get things done by motivating people and delegating responsibility.

As you consider this question, think about whether your style will let you work hatppily and effectively within the organization.

13. Are you a good manager? Can you give me some examples? Do you feel that you have top managerial potential?

Keep your answer achievementand ask-oriented. Rely on examples from your career to buttress your argument. Stress your experience and your energy.

14. What do you look for when You hire people?

Think in terms of skills. initiative, and the adaptability to be able to work comfortably and effectively with others. Mention that you like to hire people who appear capable of moving up in the organization.

15. Have you ever had to fire people? What were the reasons, and how did you handle the situation?

Admit that the situation was not easy, but say that it worked out well, both for the company and, you think, for the individual. Show that, like anyone else, you don't enjoy unpleasant tasks but that you can resolve them efficiently and -in the case of firing someone- humanely.

16. What do you think is the most difficult thing about being a manager or executive?

Mention planning, execution, and cost-control. The most difficult task is to motivate and manage employess to get something planned and completed on time and within the budget.

17. What important trends do you see in our industry?

Be prepared with two or three trends that illustrate how well you understand your industry. You might consider technological challenges or opportunities, economic conditions, or even regulatory demands as you collect your thoughts about the direction in which your business is heading.

18. Why are you leaving (did you leave) your present (last) job?

Be brief, to the point, and as honest as you can without hurting yourself. Refer back to the planning phase of your job search. where you considered this topic as you set your reference statements. If you were laid off in an across-the-board cutback, say so; otherwise, indicate that the move was your decision, the result of your action. Do not mention personality conflicts.

The interviewer may spend some time probing you on this issue, particularly if it is clear that you were terminated. The "We agreed to disagree" approach may be useful. Remember hat your references are likely to be checked, so don't concoct a story for an interview.

19. How do you feel about leaving all your benefits to find a new job?

Mention that you are concerned, naturally, but not panicked. You are willing to accept some risk to find the right job for yourself. Don't suggest that security might interest you more than getting the job done successfully.

20. In your current (last) position, what features do (did) you like the most? The least?

Be careful and be positive. Describe more features that you liked than disliked. Don't cite personality problems. If you make your last job sound terrible, an interviewer may wonder why you remained there until now.

21. What do you think of your boss?

Be as positive as you can. A potential boss is likely to wonder if you might talk about him in similar terms at some point in the future.

22. Why aren't you earning more at your age?

Say that this is one reason that you are conducting this job search. Don't be defensive.

23. What do you feel this position should pay?

Salary is a delicate topic. We suggest that you defer tying yourself to a precise figure for as long as you can do so politely. You might say, "I understand that the range for this job is between $______ and $______. That seems appropriate for the job as I understand it." You might answer the question with a question: "Perhaps you can help me on this one. Can you tell me if there is a range for similar jobs in the organization?"

If you are asked the question during an initial screening interview, you might say that you feel you need to know more about the position's responsibilities before you could give a meaningful answer to that question. Here, too, either by asking the interviewer or search executive (if one is involved), or in research done as part of your homework, you can try to find out whether there is a salary grade attached to the job. If there is, and if you can live with it, say that the range seems right to you.

If the interviewer continues to probe, you might say, "You know that I'm making $______ now. Like everyone else, I'd like to improve on that figure, but my major interest is with the job itself." Remember that the act of taking a new job does not, in and of itself, make you worth more money.

If a search firm is involved, your contact there may be able to help with the salary question. He or she may even be able to run interference for you. If, for instance, he tells you what the position pays, and you tell him that you are earning that amount now and would Like to do a bit better, he might go back to the employer and propose that you be offered an additional 10%.

If no price range is attached to the job, and the interviewer continues to press the subject, then you will have to restpond with a number. You cannot leave the impression that it does not really matter, that you'll accept whatever is offered. If you've been making $80,000 a year, you can't say that a $35,000 figure would be fine without sounding as if you've given up on yourself. (If you are making a radical career change, however, this kind of disparity may be more reasonable and understandable.)

Don't sell yourself short, but continue to stress the fact that the job itself is the most important thing in your mind. The interviewer may be trying to determine just how much you want the job. Don't leave the impression that money is the only thing that is important to you. Link questions of salary to the work itself.

But whenever possible, say as little as you can about salary until you reach the "final" stage of the interview process. At that point, you know that the company is genuinely interested in you and that it is likely to be flexible in salary negotiations.

24. What are your long-range goals?

Refer back to the planning phase of your job search. Don't answer, "I want the job you've advertised." Relate your goals to the company you are interviewing: 'in a firm like yours, I would like to..."

25. How successful do you you've been so far?

Say that, all-in-all, you're happy with the way your career has progressed so far. Given the normal ups and downs of life, you feel that you've done quite well and have no complaints.

Present a positive and confident picture of yourself, but don't overstate your case. An answer like, "Everything's wonderful! I can't think of a time when things were going better! I'm overjoyed!" is likely to make an interviewer wonder whether you're trying to fool him . . . or yourself. The most convincing confidence is usually quiet confidence.

2.用Java Bean读写中文也能成功！

哈哈，已经成功写入中文啦！o(∩_∩)o...

【总结】
1.数据库字符集需设定为utf8格式
可以在安装mysql时指定，也可以在建立数据库时指定整个库的字符集：
如：

1CREATE DATABASE cr_db  DEFAULT CHARACTER SET utf8 default collate utf8_general_ci;

这样整个cr_db库中的每个均是utf8字符集了。
2.设定names为gbk
3.连接数据库时指定连接方式useUnicode=true&characterEncoding=utf-8
