1. will vim write BOM when writing to unicode files? or is there any
options for that?
:setlocal bomb
When opening a Unicode file, Vim will set or clear the buffer-local
'bomb'
option according to the presence or absence of a BOM. That option is
irrelevant for non-Unicode files. You can also set or clear it manually.
When
creating a new Unicode file from scratch, a BOM will be set, or
not,depending
on the corresponding global setting, so if you want your new Unicode
files to
be created with a BOM, you may add
:setglobal bomb
to your vimrc.
Thanks, it seems that BOM is not written by default and can be set only
globally for all unicode encoding.
But the problem is: my gcc 4.0 will complain about BOM for utf-8 source
file, while ucs-2le must have a BOM so that vim can recognize it without
adding the ucs-2le in fencs (ucs-2le should never be added into fencs
though, since most characters in cpxxx are valid and it is likely to mess
things up).
Is there anyway to do BOM setting only for particular unicode encoding like
the following?
when write utf-8 files, do not write the BOM.
when write ucs-2 files, write the BOM. (it should happen even if the file
opend as utf-8 then :set fenc=ucs-2le and then :write)

Sincerely, Pan, Shi Zhu. ext: 2606
autocmd BufWritePre * if &fenc ==? 'utf-8' || &fenc ==? 'utf8' |
\ setlocal nobomb |
\ elseif &fenc =~? '^u' | setlocal bomb | endif
... will clear 'bomb' just before writing UTF-8 files and set it just before
writing other Unicode files (UCS-2, UCS-4 or UTF-16, UTF-32, of any
endianness; I'm not speaking here of the latest PRC encoding, GB18030 I think
it is called, which is, strictly speaking, also a Unicode encoding).
Best regards,
Tony.
