Why QString not use QTextCodec::codecForLocale by default ?
-
Currently,the QString cannot display correctly multi-byte characters like Chinese.(Tested on WinXP ,Chinese Version)
To solve this problem,we must add code "QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale)" in every program .

Because your program will run OK on a Chinese Windows XP, but not on a French one. This codecForCStrings thing is runtime dependent.
The real solution to your problem would be to save your source files in UTF-8 and use QString::fromUtf8(...) or even better, QObject::trUtf8("") for all your string literals so that you can easily translate your app afterwards and deploy it anywhere, even on other platforms.

As it's nearly always wrong to use following line
@
QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale());
@in a real word and cross-platform application.
