Re: Why use the unicode version of the api?

Sorry, it sounds like we're talking at cross purposes Thorsten. My point was
that there is an ANSI code page for each MBCS (incl. SBCS/DBCS), and that's
set as part of your locale configuration. Hence, not all ANSI character sets
have 1 byte-per-character -- it depends where you are. In general, the ANSI
code pages just deal with the local characters, plus 7-bit ASCII, but as you
say, they don't cope with all multi-national characters, whereas Unicode
does. I think that is the point you were making yourself.
