It seems ok. I'm not sure that it is better for human reading, but I
suppose you could use ".escape('unicode_escape')" or 'string_escape'.

That gives:
>>> u'\xff'.encode('unicode_escape')
'\\xff'

Which I believe means it will leave most readable characters alone, and
only escape the unreadable ones.
