I see there have been changes since I started the review.

The only one that caught my attention was in gen-unicode-ctype.py.

I think the single loop in read_input_file would be better split into
multiple loops, one for head, one to skip to tail, one for tail.

Also consider using line.startswith instead of regexps for the
end-of-head and beginning-of-tail markers, unless that risks matching
unintended lines.

Finally, consider returning a tuple instead of modifying the global
variable.

It could end up like this:

def read_input_file(filename):
  head = tail = ''
  with open(filename, mode='r') as file:
    for line in file:
      match = re.match(
         r'^(?P<key>date\s+)(?P<value>"[0-9]{4}-[0-9]{2}-[0-9]{2}")',
         line)
      if match:
        line = match.group('key') + '"{:s}"\n'.format(time.strftime('%Y-%m-%d'))
      head = head + line
      if (line.startswith('LC_CTYPE'))
        break
    for line in file:
      if (line.startswith('translit_start'))
        tail = line
        break
    for line in file:
      tail = tail + line
  return (head, tail)
   
...

  (i18n_file_head, i18n_file_tail) = read_input_file(args.input_file)
