Charset feature is available for each style over the entiredocument. If, for
example, you were Icelandic and writing a programfor use by Russian people, you
could specify that identfiers use theISO8859-1 character set but strings be in
KOI-8:
Alþjóðasamstarf = "Русский Текст"

There are three functions (DrawTextNoClip, DrawTextClipped,
andDrawTextTransparent) that are quite similar and each will have to havethis
change so it'd be better to extract this logic into anotherfunction. If you
don't do this, I'll try to before committing.
Another issue is that there are various problems with the
differentplatforms. Very long text is often badly displayed or disappears.
Iexpect there are more problems when displaying Unicode strings onWindows 9x
then there are for ANSI strings.

I'm not so sure: Windows 9x is a minority platform with adecreasing user
base. The set of Latin character set Windows 9x usersthat wish to edit CJK text
would be quite limited. I could imagineuses in a cost-constrained market such
as education.

Try writing a test program that checks the result of passing all256
potential lead byte values into IsDBCSLeadByteEx along with yourcode page.
