Reorder font characters (Dirty work)

I got some TTF files which have broken character placement – the cyrillic letters were at the
Latin-1 Supplement
block of the Unicode table. However I tried (different keyboard layouts, locales, etc.) I couldn’t input those characters anywhere, hence I was not able to use the TTF fonts.

I hacked up a python script that tries to copy the characters from where they are located in the broken files to their right position in the Unicode table (starting from 0×410).
The script uses the fontTools library and is really a dirty piece of work (it even swears, sometimes) as it just skips files where an exception is thrown from the fontTools library.
Honestly, I have little idea why some of the files corrupt the TTFile object character maps (tables), but I’m glad I got most files fixed.
Also, I’m not really sure what are the different cmap “formats” that are located in every TTFile object. But I guess it’s ok as long as I got something working.

#!/usr/bin/env python
from fontTools import ttLib
import getopt
import sys
def fixFont(filename):
    try:
      ttf = ttLib.TTFont(filename)
    except IOError:
      print filename + ' does not exist. Skipping to next file.'
      return
    # There are a few cmap tables inside a ttf object (in different 'formats'), but they apparantely are all synced with each other
    for ti in range(0,3):
      try:
        cmap = ttf['cmap'].tables[ti].cmap
      except Exception:
        print 'Fucked up stuff.. Skipping.'
        return
      # letter count -- small + capital letters
      lc = 62
      # in the broken ttfs, cyrillic chars start from a broken index
      broken = 0xc0
      # where cyrillic chars should start from in the fixed ttf
      fixed = 0x410
      #just copy all the cyrillic chars to where they belong
      for b,f in zip(range(broken,broken+lc+1),range(fixed,fixed+lc+1)):
        try:
          cmap[f] = cmap[b]
        except KeyError:
          import fontTools.unicode
          print 'The font does not contain the character ' + fontTools.unicode.Unicode[b] + '. Skipping to next character.'
      newfname = filename[:-4]+'_fixed.'+'ttf'
      try:
        ttf.save(newfname)
        return
      except Exception:
        print 'Trying another table...'

if __name__ == "__main__":
  for filename in sys.argv[1:]:
    if filename.lower()[-3:] != 'ttf':
      print filename + ': not a TTF file. Skipping to next file.'
    else:
      fixFont(filename)
