PyUnicodeWriter currently overallocates the internal buffer by 25%. On Windows, PyUnicodeWriter is slower than PyAccu API. With an overallocation factor of 50%, PyUnicodeWriter is fastter.

See this message for the benchmark:
http://bugs.python.org/issue19513#msg202312

We might also change the factor on all platform, performances are almost the same with a factor of 25% or 50% on Linux.
