How to deal with Unicode

[Barry]

Hi group,

As I found out
Boost has utf8_codecvt_facet

So is there any library completely support for all UTF in this way

or any other way to deal with Unicode more elegantly?

How ICU supports C++ io stream?

Super. I didn't know that.

The Dinkumware implementation of the standard library reportedly has
fairly complete support for Unicode.

or any other way to deal with Unicode more elegantly?

Depends how much of Unicode functionality you need. E.g., UCS2 is easy.

Cheers, & hth.,

well, I'm student
so language selection is not critical for me,
When come to Unicode issue, I choose Java or C#, I really appreciate
their native support for Unicode. Together with string and IO.

I just downloaded ICU yesterday.
with a quick view, I did't see how ICU works with C++ io streams using
codecvt.
If fully Unicode support needs different String and IO implementation.
that's really painful. Then we have to modify a lot of code to bridge
std::xstring and std::ioxxx with the new String and IO supporting Unicode.

There are two ways (that I know of, I have not made much use of Unicode)
to handle Unicode in C++, either use the wide verions (wstring, wcout,
etc.) for UTF-16 or UTF32 (depends on the platform) or use the normal
strings ect. for UTF-8. If you use normal strings just remember that
size() does not represent the number of characters (or whatever it's
called) but rather the number of bytes.
