OK.
Thanks, I hope DIRegEx closed source doesn't have this too.

OK, understand.
The next question to this:
what if I use the codepage, which is double-byte, such as Chinese Big5;
the single byte passed to MultiByteToWideChar will give wrong result. You'll
get wrong converted result with such xxx_mbtowc. Is this right?
