Probably I have implemened a two-byte UTF-8 encodings. How much bytes use each 
Chinese character?

I read the source code, no problem, the highest two bits of  utf-8 first byte 
are all 1(first byte may is 0xc0, 0xe0, 0xf0), but the display is a problem, 
but program may crash for segment fault. I can only modify the source code to 
prohibit input Chinese characters, it is good to me, because All commands are 
English letters, I just to prevent the input Chinese, program error.

Hi

I have made some changes to sourcecode to fix the problem.

Please try it on your 3-byte utf8 locale. I have tested it using 2-byte locale 
only.
If it's still broken send me your locale settings to reproduce problem.

Try git revision 21653aac8728 or 1.6 git branch. You can find git repository at 
https://src.libcode.org/klish

Thanks.

Sorry, i download  revision 21653aac872, but the problem is not solved. I use 
virtual box vm install centos 6.4 64 bit system. The var LANG=zh_CN.UTF-8. I 
use vm or secureCRT(ssh) may correctly input and display chinese characters, 
but klish is not.
problem:
1) display is not correct eg. # ?J??
2) Move the cursor is not corect, by letter not by chinese characters .  eg. # 
?J?-四J??
3) delete the command , Either delete incomplete, or deletes prompt. 
4)one chinesec characters display four byte. 
eg. #中 -> # ?J?- .

    ctrl+u double free()  now is correct.

What the right way to install chinese? May be some manual page...
I can create terminal with zh_CN locale and can see chinese characters but 
can't enter them.

In gnome-control panel I add chinese for switching input method but it allow to 
enter english characters but not chinese. it's strange for me.

Accepted. I can reproduce it.
Oh....
Chinese chars use two char positions for one symbol
