Category: Library (Lib) Group: None Status: Open Resolution: None Priority: 5 Submitted By: Walter Dörwald (doerwalter) Assigned to: Nobody/Anonymous (nobody) Summary: Speedup PyUnicode_DecodeCharmap Initial Comment: This patch speeds up PyUnicode_DecodeCharmap() as discussed in the thread: http://mail.python.org/pipermail/python-dev/2005-October/056958.html It makes it possible to pass a unicode string to cPyUnicode_DecodeCharmap() in addition to the dictionary which is still supported. The unicode character at position i in the string is used as the decoded value for byte i. Byte values greater that the length of the string and u"\ufffd" characters in the string are treated as "maps to undefined". ---------------------------------------------------------------------- >Comment By: M.-A. Lemburg (lemburg) Date: 2005-10-05 19:50 Message: Logged In: YES user_id=38388 The patch looks good, but I'd still like to see whether Hye-Shik's fastmap codec wouldn't be a better and more general solution since it seems to also provide good performance for encoding Unicode strings. That said, you should use a non-code point such as 0xFFFE for meaning "undefined mapping". The Unicode replacement character is not a good choice as this is a very valid character which often actually gets used to replace characters for which no Unicode code point is known. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1313939&group_id=5470 _______________________________________________ Patches mailing list [email protected] http://mail.python.org/mailman/listinfo/patches
