if has("multi_byte")
    set encoding=utf-8
    " English messages only
    "language messages zh_CN.utf-8
  
    if has('win32')
        language english
        let &termencoding=&encoding
    endif
  
    set fencs=ucs-bom,utf-8,gbk,cp936,latin1
    set formatoptions+=mM
    set nobomb " 不使用 Unicode 签名
  
    if v:lang =~? '^\(zh\)\|\(ja\)\|\(ko\)'
        set ambiwidth=double
    endif
else
