Thanks for the quick update,
I confirm the fix for both issues;
just another finding (while testing the behaviour mentioned previously - msg91917)

The property name normalisation seem to be much more robust now, I just encountered an encoding error using a rather artificial input (in python 2.5, 2.6):

>>> regex.findall(ur"\p{UppercaseÄÄÄLetter}", u"QW\p{UppercaseÄÄÄLetter}as")

Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    regex.findall(ur"\p{UppercaseÄÄÄLetter}", u"QW\p{UppercaseÄÄÄLetter}as")
  File "C:\Python25\lib\regex.py", line 213, in findall
    return _compile(pattern, flags).findall(string, overlapped=overlapped)
  File "C:\Python25\lib\regex.py", line 599, in _compile
    parsed = _parse_pattern(source, info)
  File "C:\Python25\lib\regex.py", line 690, in _parse_pattern
    branches = [_parse_sequence(source, info)]
  File "C:\Python25\lib\regex.py", line 702, in _parse_sequence
    item = _parse_item(source, info)
  File "C:\Python25\lib\regex.py", line 710, in _parse_item
    element = _parse_element(source, info)
  File "C:\Python25\lib\regex.py", line 837, in _parse_element
    return _parse_escape(source, info, False)
  File "C:\Python25\lib\regex.py", line 1098, in _parse_escape
    return _parse_property(source, info, in_set, ch)
  File "C:\Python25\lib\regex.py", line 1240, in _parse_property
    raise error("undefined property name '%s'" % name)
error: <unprintable error object>
>>> 

Not sure, how this would be fixed (i.e. whether the error message should be changed to unicode, if applicable).

Not surprisingly, in python 3.1, there is a correct message at the end:

regex.error: undefined property name 'UppercaseÄÄÄLetter'
