Faster (5x) charmap codec decode and encode in Pyrex
Fastcharmap is about 5 times faster than Python’s charmap routines.
Fastcharmap inserts faster code that works when unicode() or “”.encode are called. Installation requires a binary distribution or a C compiler; Pyrex is required for changes to the source. Python’s developers are working on faster charmap codecs for a future version of Python; fastcharmap may be useful until then.
