I disagree. But if you'd rather see the character (or a replacement character,
or possibly an empty box, depending on your environment's text rendering
capabilities), it's a bit easier than writing that big function:

>>try: open(u'\N{WHITE SMILING FACE}')

.... except IOError, e: print str(e).decode(' unicode-escape')
....
[Errno 2] No such file or directory: u'☺'

Yes, this is a more concise solution. Thank you.
