查看vim的菜单配置

[talen@fedora ~]$ ls /usr/share/vim/vim73/lang/ |grep menu_zh_cn
menu_zh_cn.18030.vim
menu_zh_cn.cp936.vim
menu_zh_cn.gb2312.vim
menu_zh_cn.gbk.vim
menu_zh_cn.utf-8.vim
没有utf8,只有utf-8，只要创建一个软链接就可以了
[talen@fedora ~]$ cd /usr/share/vim/vim73/lang/
[talen@fedora lang]$ sudo ln -s menu_zh_cn.utf-8.vim menu_zh_cn.utf8.vim

重新打开gvim，清爽的菜单。
