为什么Necessitas不支持在我的Android Qt应用程序中显示汉字？

Question

Necessitas is the codename for the port of Qt on the Android Operating System and of the user-friendly Qt Creator Integration with Android. Now , using Necessitas (QT for Android),I can run & debug my Qt Applications on Android Devices. But I got these log when I want to setText("中文") on QLabel.
Why can Necessitas not support to display Chinese characters in my qt application for android ? Or, what steps do I have less ?

Answer 1

Is this question ambiguous, vague, incomplete, overly broad, or rhetorical ? Now I'm sure that it doesn't support at all.
