Description
During investigation of a KDE bug (https://bugs.kde.org/show_bug.cgi?id=250728), we've found an apparent locale sensitivity in QFontDatabase, at least on Linux (original reporter identified the problem on Ubuntu 10.04.1 LTS, I've reproduced it on Fedora 13).
The result of the styles() method appears to vary according to the LC_CTYPE environment variable, for one specific font (NSimSun). It works correctly, except for Chinese language locales (e.g. LC_CTYPE=zh_CN.UTF-8). In those cases, styles() returns an empty QStringList.
The attached patch (for the qfontdatabase auto tests) shows the problem. It passes for the C locale, and most other locales that I tried.
When run as
[bradh@fedora13 qfontdatabase]$ LC_CTYPE=zh_CN.UTF-8 ./tst_qfontdatabase
