Following a discussion on reddit it seems that the unicode case conversion algorithms are not being followed. $ python3.0 Python 3.0rc1 (r30rc1:66499, Oct 10 2008, 02:33:36) [GCC 4.0.1 (Apple Inc. build 5488)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> x='ß' >>> print(x, x.upper()) ß ß This conversion is correct as defined in UnicodeData.txt however http://unicode.org/Public/UNIDATA/SpecialCasing.txt defines a more complete set of case conversions. According to this file "ß".upper() should be "SS". Presumably Python simply isn't using this file to create it's mapping database.

This conversion is correct as defined in UnicodeData.txt however
http://unicode.org/Public/UNIDATA/SpecialCasing.txt defines a more
complete set of case conversions.

According to this file "ß".upper() should be "SS". Presumably Python
simply isn't using this file to create it's mapping database.
