Better accessibility for inexperienced users.
Adobe’s Acrobat reader offers facilities for electronic presentations

Limitation of pdfTeX

ubuntu 下 latex 中文支持script ＆ samples

By Jeffye, on February 22nd, 2010

介绍如何在ubuntu 下按章cjk 支持，一下脚本在ubuntu 9.10 + kile 下测试好使。

latex 下安装中文支持，需要安装一系列宏包，然后拷贝生成字体什么的，甚是繁琐。一步抄作出问题，会浪费很多时间。

不如写成一个script， shell 脚本。出问题，或机器重装，运行此脚本即可，一劳永逸。

备忘。 脚本下载：install_cjk

samples :
\documentclass{article}
\usepackage{CJK}
\begin{document}
\begin{CJK}{UTF8}{song}
这是so8848
\end{CJK}
\end{document}
