[SOLVED] How to Make a UTF-8 Compatible Application

I have been building a small GUI in Qt and have run into this issue: my widgets are not UTF-8-compatible. Here's what happens if I set my window title to "cliché:"

Does anyone have any ideas? I'm using Qt 4.5 on KDE 4.3

Re: [SOLVED] How to Make a UTF-8 Compatible Application

The title bar of your window is not a widget, but a feature of your window manager.  You can verify this by using a different window manager or changing the fonts.  Openbox is working for me with default font settings; wmii does the same thing yours does.

The solution?  Don't use UTF-8 in window titles.  You can't predict what fonts or window managers your target audience will be using.  (Real widgets, like buttons and labels, should behave.)

Actually, I'm having the same problem with a QPushButton (whether I use tr() or QString()):

Any ideas? Also, in case it matters, my locale is set to 'en_GB.UTF-8 UTF-8' in /etc/locale.gen and 'en_GB.utf8' in /etc/rc.conf.

Are you sure QT is UTF-8—compatible?

(I wouldn't know, since I don't do any GUI programming.)

Thanks for all the tips. I found what I needed. For anyone else who comes to this page looking for the answer, it turns out you need to use "QString::fromUtf8()" to solve the problem.
