[New-bugs-announce] [issue15612] Rewriter StringIO to use the _PyUnicodeWriter API

[STINNER Victor]

New submission from STINNER Victor:

Attached patch rewrites the C implementation of StringIO to use the _PyUnicodeWriter API instead of the PyAccu API. It provides better performance when writing non-ASCII strings.

The patch adds new functions:

 - _PyUnicodeWriter_Truncate()
 - _PyUnicodeWriter_WriteStrAt()
 - _PyUnicodeWriter_GetValue()
