In fact, many of Japanese FreeBSD users seems to have been suffered
from the problem:

 (even if you can't read japanese, you still can discover some
alphabets on the page. :)

I didn't aware of the problem because I'm using UTF-8 locale, but
few friends of mine asked a help to me.

platform.  mblen(NULL, 0); is clearly defined in POSIX as a reset
method.


Thanks,
