linux下vim想要解决编码问题，我相要在vim的配置文件中加入下面几句话：

set fileencoding=gb2312
set fileencodings=utf-8, gbk, utf-16, gb2312, big5
set ambiwidth=double

在$home/.vimrc(_vimrc)或在vim安装目录的_vimrc(.vimrc)文件中加入以下内容

" multi-encoding setting
if has("multi_byte")
"set bomb
set fileencodings=ucs-bom,utf-8,cp936,gb18030,big5,euc-jp,sjis,euc-kr,ucs-2le,latin1
" CJK environment detection and corresponding setting
if v:lang =~ "^zh_CN"
" Use cp936 to support GBK, euc-cn == gb2312
set encoding=cp936
set termencoding=cp936
set fileencoding=cp936
elseif v:lang =~ "^zh_TW"
" cp950, big5 or euc-tw
" Are they equal to each other?
set encoding=big5
set termencoding=big5
set fileencoding=big5
elseif v:lang =~ "^ko"
" Copied from someone's dotfile, untested
set encoding=euc-kr
set termencoding=euc-kr
set fileencoding=euc-kr
elseif v:lang =~ "^ja_JP"
" Copied from someone's dotfile, untested
set encoding=euc-jp
set termencoding=euc-jp
set fileencoding=euc-jp
endif
" Detect UTF-8 locale, and replace CJK setting if needed
if v:lang =~ "utf8$" || v:lang =~ "UTF-8$"
set encoding=utf-8
set termencoding=utf-8
set fileencoding=utf-8
endif
else
echoerr "Sorry, this version of (g)vim was not compiled with multi_byte"
endif


"关掉备份文件
