Chinese Charactor Configuration on Fedora 11
最新的更新版本请看: Fedora 中文字体设置. Updated on 26 Feb. 2010 ∞ 使用Linux时我个人倾向使用英文环境系统，而Fedora11在英文环境下中文字体有时会不太好看，经常遇到需要字体优化美化的问题。 以下是我的配置方案，经测试效果还算不错，解决了Fedora 11 中文字体难看的问题： 方案1：使用uming和ukai字体，即AR PL UMing CN等。 关键是使用的字体包如下： 首先要安装这两个字体： cjkuni-ukai-fonts cjkuni-uming-fonts 然后配置一下~/.fonts.conf文件. 使sans-serif serif monospace字体中文使用uming/ukai即可. 我的.fonts.conf文件可以从这里下载(两种选择, 我喜欢前者): http://github.com/zma/config_files 使用Liberation和uming/ukai字体: .fonts.cofn.liberation 使用dejavu和uming/ukai字体: .fonts.conf.dejavu 下载后放到自己的$HOME下改名为.fonts.conf就可以了。 使用uming字体效果如下（请放大后看效果）： 方案2：安装文泉驿字体，这个非常简单，安装相应包即可了。 如果喜欢其它的字体选择性的安装上就可以了，只要注意只安装自己需要的就行了。有人使用微软雅黑字体，首先这是侵权的，其次开源的字体做得其实已经很不错了。 最后将字体平滑选项打开, KDE和gnome都有相关设置方法。 以上内容只是针对使用xft字体系统的设置。对于使用核心字体系统的X程序来说字体依然会出现很丑的情况。 下面是针对emacs的设置方法： 首先需要安装这个字体包： xorg-x11-fonts-misc 注意到在中文系统下emacs的中文显示非常好，而在英文环境中去非常差，我们可以利用这一点，在运行emacs前首先将系统环境设为中文即可。 在~/bin/下建立一文件ema 内容如下： #!/bin/bash rm -f ~/.emacs ln -s ~/.emacs.x ~/.emacs LANG=zh_CN.UTF-8 emacs […]
