Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Library Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Tony Nelson (tony_nelson) Assigned to: Nobody/Anonymous (nobody) Summary: mac_roman codec missing "apple" codepoint Initial Comment: The mac_roman codec is missing a single codepoint for the trademarked Apple logo (0xF0 <=> 0xF8FF per Apple docs), which prevents round-tripping of mac_roman text through Unicode. Adding the codepoint as a private encoding (per Apple) has no trademark implications, only the character itself, in a font, would have such issues. I'm using Python 2.3, but AFAICT it is an issue in later Python versions as well. ---------------------------------------------------------------------- >Comment By: M.-A. Lemburg (lemburg) Date: 2005-10-04 23:48 Message: Logged In: YES user_id=38388 Tony, comment like yours are not very helpful. Python's codecs rely on facts defined by standards bodies, e.g. the Unicode consortium, ISO, etc.. If you don't present proof of your claim then there's nothing much we can do about your particular problem. Fortunately, proof isn't hard to find in this case: http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/ROMAN.TXT Looks like Apple added the mapping sometime after the codec was created. Walter: it is common for companies to add their logos as private Unicode characters. This happens a lot in the Asian world. Of course, interop isn't great, but at least you don't lose information by converting to Unicode. Tony: Python is not damaging your data - the codec will raise an exception in case that particular character is converted to Unicode. Please recreate the codec using gencodec.py (which you can find the Tools/ directory) and add it as attachement to this bug report. Thanks. ---------------------------------------------------------------------- Comment By: Tony Nelson (tony_nelson) Date: 2005-10-04 22:41 Message: Logged In: YES user_id=1356214 It isn't Python's job to tell people what characters they are allowed to use. Apple defined the codepoint and its mapping to Unicode. Python is not the Unicode Police, and should not damage the data it was given just to prove a point. Damaging the user's data isn't very "batteries included". ---------------------------------------------------------------------- Comment By: Walter Dörwald (doerwalter) Date: 2005-10-04 20:07 Message: Logged In: YES user_id=89016 The codepoint 0xF8FF is in the Private Use Area, so this is not an official Unicode character, and for other uses 0xF8FF might mean something completely different. So I think this mapping shouldn't be added to mac_roman. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1313051&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
