I have a very basic qt program. It works very well on emulator. The problem is about text display in QLabel, QButton and any Widget. I have a Nokia 5230 international edition with all languages supports. The program works well. All language strings are displayed correctly. But I have a N97 us version, which only support five language. No text is displayed at all in all widgets, including English. In some situations, string will be displayed as KKKKKKK, with or without tr(). Is there any body can tell me what's wrong? Thanks.
