Re: gawk: length return incorrect value when MB_CUR_MAX > 1

Kimura,

It sounds like you prefer Paul's patch?  I guess a valid question is:

> I found mbrtowc() store L'\0' to &wc when detect '\0'.

Is this portable behavior? I.e., defined by the ISO C standard?

In any case, I'll apply one patch or the other; Paul's looks preferable
if it's the most portable.

Thanks!

Arnold
