This is what I am using (need +python):
" %xx -> 对应的字符(到消息)[[[2
function Lilydjwg_hexchar()
let chars = Lilydjwg_get_pattern_at_cursor('\(%[[:xdigit:]]\{2}\)\
+')
if chars == ''
echohl WarningMsg
echo '在光标处未发现%表示的十六进制字符串！' "echo that the form of string cannot be
found there.
echohl None
return
endif
let str = substitute(chars, '%', '\\x', 'g')
exe 'py print ''' . str . ''''
endfunction
" 取得光标处的匹配[[[2
function Lilydjwg_get_pattern_at_cursor(pat) "This is a function I
borrowed from another plugin
let col = col('.') - 1
let line = getline('.')
let ebeg = -1
let cont = match(line, a:pat, 0)
while (ebeg >= 0 || (0 <= cont) && (cont <= col))
let contn = matchend(line, a:pat, cont)
if (cont <= col) && (col < contn)
let ebeg = match(line, a:pat, cont)
let elen = contn - ebeg
break
else
let cont = match(line, a:pat, contn)
endif
endwh
if ebeg >= 0
return strpart(line, ebeg, elen)
else
return ""
endif
endfunction
nmap <silent> t% :call Lilydjwg_hexchar()<CR>
After writing this to .vimrc, when I move the cursor to where the %xx
string is and press t%, I can see the decoded string.
Or you can just use a program called ascii2uni, eg:
echo %E9%A6%AC | ascii2uni -q -a J
and the output is 馬. You can combine this with the filter (:h filter)
feature of Vim to get lines of characters converted directly from
within Vim.
