linux下的中文字体确实是一个比较令人头大的地方，尤其是在gentoo下，每次编译过fontconfig后总是会出一点状况，那么为了长期稳定使用自己设置好的中文字体，那么除了把配置文件放在用户本地目录下外，另一个办法就是把文件备份。中文字体用simsun.ttf等。
在用户本地目录下~/.fonts.conf

在/etc/fonts/conf.d/下有很多链接，整理出需要的如下：
10-no-sub-pixel.conf 20-unhint-small-vera.conf 50-user.conf
10-sub-pixel-bgr.conf 40-generic.conf 51-local.conf
10-unhinted.conf 49-sansserif.conf
经过这样的设置后不但系统的中文显示没有任何问题，而且firefox的中文显示也和系统的完全统一了。
