Linux下字体配置

Posted 2020-12-20 戊戌乡人

fontconfig

fontconfig会优先读 $XDG_CONFIG_HOME/fontconfig/fonts.conf 的配置，因此自定义配置优先级更高。没有才会读 /etc/fonts/fonts.conf

之前使用texlive将textlive的字体做为系统字体后，系统的字体显示就变的混乱了，chrome网页中同一段文本既有黑体，又有宋体，因此需要重新设置字体配置。

fc-match -a <字体名> 查询字体名对应的字体文件，会出来一大堆，一般会用第一个。目前猜测是如果第一个中没有所要字形，就会顺序用第二个，依次类推，直到字形被渲染。应该就是网页中同一段部分字体是楷体，部分是黑体的原因。

一般重点是sans-serif，serif和monospace三类字体，自己写fonts.conf 把系统中已有字体加到匹配列表最前面。

修改完fonts.conf后，需要运行 fc-cache -fv
