[New-bugs-announce] [issue13417] faster utf-8 decoding

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

PEP 393 and the need for a two-pass decoding process has made utf-8 decoding much slower, especially with the current generic implementation. Attached patch makes utf-8 more than twice faster, which means we're around 10-20% slower than 3.2 on non-trivial cases.
