Great!
I was really afraid I won't see this in this year.

I think this would be the best solution. This would make possible to fix
any bugs and design problems in Unicode strings before Qt 2.0
Q2String could be used now only in "unstable" apps, which don't have to be
binary compatible.


I would really like to see Unicode in Qt 1.41. It could really help KDE
becone really international.

Is there any charset conversion support in Qt? In fact I would rather not
like it. It can be done better on a highier level - in KDE. And I wouldn't
like it done as in current QString, where charsets are identified only by
enums.

It seems I would have to change KDE charset support classes to work with
Qt Unicode, but it shouldn't be hard to do.

Greets,
