69ed0f4c86 Use PyUnicode_READ() instead of PyUnicode_READ_CHAR() 
"PyUnicode_READ_CHAR() is less efficient than PyUnicode_READ() because it calls
PyUnicode_KIND() and might call it twice." according to its documentation.

cd777eaf53 Issue #17615: Comparing two Unicode strings now uses wmemcmp() when possible 
wmemcmp() is twice faster than a dummy loop (342 usec vs 744 usec) on Fedora
18/x86_64, GCC 4.7.2.

cfc4c13b04 Add _PyUnicodeWriter_WriteSubstring() function 
Write a function to enable more optimizations:

 * If the substring is the whole string and overallocation is disabled, just
   keep a reference to the string, don't copy characters
 * Avoid a call to the expensive _PyUnicode_FindMaxChar() function when
   possible

18aa4477d3 Close #16281: handle tailmatch() failure and remove useless comment 
"honor direction and do a forward or backwards search": the runtime speed may
be different, but I consider that it doesn't really matter in practice. The
direction was never honored before: Python 2.7 uses memcmp() for the str type
for example.

7ae320d667 (Merge 3.2) Issue #16455: On FreeBSD and Solaris, if the locale is C, the 
ASCII/surrogateescape codec is now used, instead of the locale encoding, to
decode the command line arguments. This change fixes inconsistencies with
os.fsencode() and os.fsdecode() because these operating systems announces an
ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.
