Python 3.3 is a language. Languages do not have timings.
CPython 3.3.0 is an implementation compiled and run under a particular 
OS and hardware. With respect to Unicode timings, especially for 
find/replace, it is obsolete. On my Win7 machine with fresh debug builds 
from the current repository, I see these times.

Python 3.3.1+ (default, May  7 2013, 14:03:12) [MSC v.1600 32 bit (Int
 >>> from timeit import repeat
 >>> repeat("a = 'hundred'; 'x' in a")
[0.19007337649622968, 0.190116721780754, 0.1900149679567562]
 >>> repeat("a = 'maçaé??'; 'é' in a")
[0.20568874581187716, 0.20568782357178053, 0.20577051776710914]

Python 3.4.0a0 (default:32067784f198, May  7 2013, 13:59:10) [MSC v.1600
 >>> from timeit import repeat

Note 1: debug builds are slower than install builds, especially for 
microbenchmarks with trivial statements. My installed 3.3.1 on a 
different machine has timings of about .1 for the ascii test. It is 
slower for the non-ascii test because the latest improvements were made 
after 3.3.1 was released.

Note 2: 3.4 has additional improvements that speed up everything, so 
that the 3.4 non-ascii time is faster that even the 3.3 ascii time.
