convert-ly incompatible with Python 2.2

[Mats Bengtsson]

Hi,

I have finally taken the time to compile the latest development version.
When trying to convert an old file containing some special characters,
I received the following error message

convert-ly -e /tmp/fonts.ly
convert-ly (GNU LilyPond) 2.5.16
Processing `/tmp/fonts.ly'...
Applying conversion: 2.5.0, 2.5.1, 2.5.2, 2.5.3, 2.5.12, 2.5.13Traceback 
(most recent call last):
  File "/space/bin/convert-ly", line 2594, in ?
    do_one_file (f)
  File "/space/bin/convert-ly", line 2527, in do_one_file
    touched = do_conversion (infile, from_version, outfile, to_version)
  File "/space/bin/convert-ly", line 2465, in do_conversion
    str = x[1] (str)
  File "/space/bin/convert-ly", line 2426, in conv
    except UnicodeDecodeError:
NameError: global name 'UnicodeDecodeError' is not defined

I use Python 2.2.2 but it seems that the current implementation in
convert-ly depends on Python version 2.3 or newer, see
http://www.python.org/doc/2.3.5/whatsnew/node11.html
I could easily make convert-ly work with my version of Python by
replacing the two occurances of "UnicodeDecodeError" by "UnicodeError"
but then it will probably not work any more with newer versions of
Python.
