Re: More Stream File and DBCS issues...

Thanks, Joe.

Should be easy enough to test, so I'll give it a shot.

I just hope when I convert it to UCS-2 and back it doesn't
mess something up that way, or I don't lose my sI and sO
characters.  :)

I'm in no way an expert on this stuff, Brad, so take it

DBCS data gets converted to code points that don't clash
with standard
single-byte data.

For the most part, standard ASCII is mapped to 00xx,
where xx is the
original ASCII hex code.  DBCS data, on the other hand,
gets converted to
values > 256.  Thus you can't have collisions.

Note that UCS-2 is ALWAYS 16 bits per character.
 Meanwhile, UTF-8 and
UTF-16, the other popular Unicode format, can contain
characters of up to
four bytes which allow for over a million characters.
 UTF is way confusing
for me, since it also allows for special "combining
characters" (a way of
specifying, for example, an umlaut along with a U).

In a nutshell, it sounds like this may convert all
characters, either SCBS or DBCS to unique values so

that

there is no way a DBCS value can contain a byte that is
equal to a SBCS value and this problem would be

eliminated?
