Archlinux 字体配置

安装好 archlinux 后，默认的字体显示效果，实在是……
按照 wiki，可以通过 AUR 安装经 Ubuntu 打过补丁的几个字体渲染包：

# yaourt -S cairo-ubuntu freetype2-ubuntu fontconfig-ubuntu(2013-05-16 经过测试，已经不需要这两个包了)

接下来，配置使用的字体。首先安装所需字体：

# pacman -S ttf-dejavu ttf-liberation wqy-zenhei ttf-arphic-ukai ttf-arphic-uming

网上很多都是说修改 /etc/fonts/local.conf  或是 /etc/fonts/conf.d/49-sansserif.conf 等系统文件，但是这样升级系统后，配置文件便会丢失。

其实只需要在 home 目录下创建 ～/.config/fontconfig/fonts.conf 文件，其编码为 UTF-8，其内容为：

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
