Re: copymemory basic question

If CopyMemory is used properly then there is no character set translation
involved at all. It's a generic API for moving amorphous memory, i.e. bytes
of data. The API itself doesn't care what the data is, and treats it
literatim. Hence, if any ANSI conversion is being done then it's because the
API declaration is wrong.
