New submission from Carl Friedrich Bolz <cfb...@gmx.de>: There seems to be a problem with some unicode character's title information:
$ python2.6 Python 2.6.2c1 (release26-maint, Apr 14 2009, 08:02:48) [GCC 4.3.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> unichr(453) u'\u01c5' >>> unichr(453).title() u'\u01c4' But the title should return the same character, according to this: http://www.fileformat.info/info/unicode/char/01c5/index.htm (I also checked the files that unicode.org provides). I tried to follow the problem a bit, it seems to come from _PyUnicode_ToTitlecase in unicodetype.c. The unicode record contains the offset of the character to its titled version. If the character is its own titled version, then the offset is zero. But zero is also used for when there is no information available, so the offset to the upper-case version of the character is used. If this is a different character (as for the example above), the result of .title() is wrong. ---------- components: Interpreter Core messages: 86163 nosy: cfbolz severity: normal status: open title: title information of unicodedata is wrong in some cases type: behavior versions: Python 2.4, Python 2.5, Python 2.6, Python 3.0 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5791> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
