Why latin-1? Try
page = unicode(page, 'cp852')

Use decode() here, not encode().
decode() goes towards Unicode
encode() goes away from Unicode
As a mnemonic I think of Unicode as pure unencoded data. (This is *not*
accurate, it is a memory aid!) Then it's easy to remember that decode()
removes encoding == convert to Unicode, encode() adds encoding ==
convert from Unicode.

When you call encode on a string (instead of a unicode object) the
string is first decoded to Unicode using ascii encoding. This usually fails.
