Chinese Charactor Configuration on Fedora 11

Posted on

最新的更新版本请看: Fedora 中文字体设置. 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): https://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 –fullheight -r $* 然后加入执行权限即可: chmod +x
