如何在vim中“自动”将euc-kr转换为utf-8？

Question

I know how to convert it manually like this: map <F4> :e ++enc=euc-kr <CR> :set fenc=utf-8 <CR> :w ++enc=utf-8 <CR> .

But, I want to convert automatically by writing conditional-statement inside .vimrc file. So, I wrote the code as below and it didn't work.

    if ($fileencoding == "euc-kr")
        ++enc=euc-kr %
        set fenc=utf-8
    endif

What was wrong and how to fix it?

Answer 1

There are two parts to it:

To allow Vim to detect the encoding automatically on :edit (so that you don't need to specify ++enc=euc-kr ), you have to adapt your 'filencodings' (plural!) option, eg:

:set fileencodings=ucs-bom,utf-8,euc-kr

In order to persist the encoding as UTF-8, the following autocmd will adapt the 'fileencoding' (singluar) for the current buffer:

:autocmd BufWritePre * if &l:fileencoding ==# 'euc-kr' | setlocal fileencoding=utf-8 | endif
