Hi Loden,
The source code you provided if not cross-platform even under Qt4.
Under Windows platform, source file is save using encoding "GBK" while
under linux platform it saved as "UTF-8"
which means you are using two sets of source code for two platforms.
In addition, these are two errors(mistakes) in your source code.
1. Q_WS_WIN should be changed to Q_OS_WIN even you are using Qt4
2. You should not call setCodecForLocale() in such cases, no mater
you are using Qt4 or Qt5.
