This function generates a table of Unicode characters in Vim so you can see how they are displayed by your system. This may be of interest to anyone using CJK characters.

Example The following will add a table showing the characters from hex 9900 to hex 9fff, inclusive:

:call GenerateUnicode(0x9900, 0x9fff)

For this to work, you will need:

:set guifont=*         "select a suitable font
:set encoding=utf-8    "set a suitable encoding
:set ambiwidth=double  "for CJK characters

If you copy the following into a file, you can type :so % (source current file) to define the function.

function! GenerateUnicode(first, last)
  let i = a:first
  while i <= a:last
    if (i%256 == 0)
      $put ='----------------------------------------------------'
      $put ='     0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F '
      $put ='----------------------------------------------------'
    endif
    let c = printf('%04X ', i)
    for j in range(16)
      let c = c . nr2char(i) . ' '
      let i += 1
    endfor
    $put =c
  endwhile
endfunction
