vim7.3 编辑中文字符的文件会显示乱码
默认编译安装vim7.3后打开含有中文字符的文件会显示乱码，google了一圈，大多都是说在配置文件中添加下面的几行就可以解决问题：
set encoding=utf-8
set fileencoding=utf-8
但我设置了之后仍然没有解决问题

...
--enable-workshop Include Sun Visual Workshop support.
--disable-netbeans Disable NetBeans integration support.
--enable-sniff Include Sniff interface.
--enable-multibyte Include multibyte editing support.
--enable-hangulinput Include Hangul input support.
--enable-xim Include XIM input support.
--enable-fontset Include X fontset output support.
...

重新配置编译选项
$./configure --enable-multibyte # 多字节编辑支持
$ make && sudo make install
