Apart from fixing the above (including the last version I posted
here, which has a catch, yes, I have "fileencodings" set to an empty
string. Why this wouldn't work if 'fencs' is not an empty string? Is
because 'fenc' will get a value *after* the autocommand is invoked?.
'Fileencodings' is the option to detect the file encoding, and
'fileencoding' is the option to set/reflect the encoding of the
current file.
In my _vimrc, I have settings like:
function! SetFileEncodings(encodings)
let b:my_fileencodings_bak=&fileencodings
let &fileencodings=a:encodings
endfunction
function! RestoreFileEncodings()
let &fileencodings=b:my_fileencodings_bak
unlet b:my_fileencodings_bak
endfunction
au BufReadPre *.gb call SetFileEncodings('cp936')
au BufReadPre *.big5 call SetFileEncodings('cp950')
au BufReadPre *.nfo call SetFileEncodings('cp437')
au BufReadPost *.gb,*.big5,*.nfo call RestoreFileEncodings()
You may use a similar way.
