Bash and multibyte characters

[Michael C . Wu]

Hello bash users:

Regarding multibyte character support, here is a feature suggestion:
Say we have two-byte characters (commonly used in Chinese/Japanese/
Korean) AA, BB, XX, and YY

The correct behavior when I have the following text:

AABBXXYY<cursor>
and I push "backspace" once
The result would be:
AABBXX

But bash does this:
AABBXXY

And we have to push the delete button again, same incorrect behavior
happens with arrow keys, ^W and etc.

Basically, bash needs to be taught about multibyte characters.
Would you mind modifying bash behavior to respect an environmental
shell variable that toggles this as well as the functionality?

Merry Christmas and thanks,

Michael
