Summary: Unicode xmlcharrefreplace produces backslash not xml style.
Initial Comment:
In Python 2.4.2 and 2.5, and maybe other versions too, the unicode string
encoder for producing xml style unicode output (example, © for copyright
symbol) produces the wrong style -- it produces backslash encoding (\xa9 for
same copyright unicode character).
Example at Python shell:
u'\u2122'.encode('unicode_escape','xmlcharrefreplace')
should produce: ™
but it produces \u2122
The same happens when it is used in a program. The print output of the encoded
unicode contains backslash encodings as though the method 'backslashreplace'
had been used.

u'\u2122'.encode('unicode_escape','xmlcharrefreplace') produces \u2122
because that's the way the unicode_escape codec outputs unicode codepoints.
For unicode_escape the xmlcharrefreplace error handler never kicks in. If
you want the error handler to kick in, you have to use an encoding that
doesn't support the character you want to encode. The best candidate is
probably ascii:
>>> u"\u2122".encode("ascii", "xmlcharrefreplace")
>>> '™'
