Read in UTF-8 file

[99miles]

Hello-
I am having trouble figuring out how to read in a UTF-8 file. Could
somebody please give me a simple example? I am using VS 6.0 writing
for windows only. The file is a zstring.dct file.
Thanks a lot-
Mac

One reads UTF-8 via any 8-bit stream system, which on VC++ is a simple
std::string, std::iostream, etc.

However, strlen() will return the number of bytes, not the number of
characters. In general the string manipulation functions will not be aware
of the difference between characters and bytes.

If you then try to display the string, that's a topic for a Win32 UI
newsgroup.

Tell them where you are getting stuck, because UTF-8 designs to be
compatible with most platforms' strings.

You need a codecvt facet that does the conversion for you. VC++ V6.0
by default does a one-to-one conversion, which is not adequate for
your needs. See our CoreX library, at our web site.

Conversion from UTF-8 to what?

Conversion from UTF-8 to what?

UCS-2 or UCS-4. From there you can go to a gazillion other codes. See
the documentation for CoreX at our web site.
