os: Ubuntu 10.10
nanny version 2.29.4

As attachment, each regulars is actually a word. it should display Monday, Tuesday, Wends day Thursday, Friday, Saturday, Sunday in Simplified Chinese. The text is generated by client/gnome/admin/src/ScheduleCalendar.py

There is no font configuration in nanny codes, so it uses the sans-serif font family according the fontconfig configuration.

In this case, fontconfig defined several fonts in sans-serif font family, file:/etc/fonts/conf.avail/69-language-selector-zh-cn.conf

                        <string>DejaVu Sans</string>
                        <string>Bitstream Vera Sans</string>
                        <string>WenQuanYi Micro Hei</string>
                        <string>WenQuanYi Zen Hei</string>

The first 2 fonts are western fonts, 3th and 4th are Chinese fonts, Ideally, the Chinese font will be matched by fontconfig if the character in the user interface is a Chinese word. the western fonts will be skipped.

Except Result:

Schedule Calendar of Nanny should uses WenQuanYi Micro Hei or WenQuanYi Zen Hei

Actaul Result:

Schedule Calendar of Nanny uses DejaVu Sans font even it is in zh_CN locales, 

Suggested solution:

1. get font by fontconfig api in zh_CN locale
2. set font matched font
