debian7 解决 vim 中文乱码

cat 正常，vim 进入档案，中文就乱码
/etc/vim/vimrc 里加入：
set fileencodings=utf-8,gb2312,gbk,gb18030
adding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, ‘Microsoft Yahei’, ‘Hiragino Sans GB’, sans-serif; letter-spacing: 0.25px; line-height: 28px; white-space: normal; background-color: rgb(246, 246, 246);”/>set termencoding=utf-8
dding: 0px; color: rgb(51, 51, 51); font-family: Helvetica, ‘Microsoft Yahei’, ‘Hiragino Sans GB’, sans-serif; letter-spacing: 0.25px; line-height: 28px; white-space: normal; background-color: rgb(246, 246, 246);”/>set encoding=prc
