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

Necessitas 是 Android 操作系统上 Qt 端口以及用户友好的 Qt Creator 与 Android 集成的代号。现在,使用 Necessitas (QT for Android),我可以运行 &在 Android 设备上调试我的 Qt 应用程序。 但是当我想在 QLabel 上 setText("中文") 时,我得到了这些日志。
为什么 Necessitas 不支持在我的 Android 版 qt 应用程序中显示汉字?或者说,我少了哪些步骤?

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 ?

这个问题是否含糊、含糊、不完整、过于宽泛或修辞?现在我确信它根本不支持。

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