UTF-32 decoder optimization in Python 3.4
From http://docs.python.org/dev/whatsnew/3.4.html#optimizations The UTF-32 decoder is now 3x to 4x faster.. Does anybody have any references to this work? All I can find is the 3.3 what's new which refers to PEP 393 (Flexible String Representation) optimizations as a result of work done by Serhiy Storchaka on issues 14624, 14738 and 15026. -- Python is the second best programming language in the world.
