Oh.  Never mind.

###
>>> x, y = u'\xf6', '\xf6
>>> x + y
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeError: ASCII decoding error: ordinal not in range(128)

Well, at least now we have a test case we can work on.  *grin*



I think that the concatentation causes Python to raise the second string y
up as a unicode string.  At least, it looks like that unicod()ing a
high-byte character can cause the encoding error:

###
>>> unicode('\xf6')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeError: ASCII decoding error: ordinal not in range(128)

I'm actually not quite sure how to solve this yet; I'm not familiar with
Unicode at all, so I think I might need to tinker with this problem a bit.
