types. Added a new API function, PyUnicode_TransformDecimalToASCII(),
which transforms non-ASCII decimal digits in a Unicode string to their
ASCII equivalents.
* PyUnicode_EncodeFSDefault(), PyUnicode_DecodeFSDefaultAndSize() and
PyUnicode_DecodeFSDefault() use the locale encoding instead of UTF-8 if
Py_FileSystemDefaultEncoding is NULL
* redecode_filenames() functions and _Py_code_object_list (issue #9630)
are no more needed: remove them
Database (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others) now accept
and return characters from the full Unicode range (Py_UCS4).
The differences from Python code are few:
- unicodedata.numeric(), unicodedata.decimal() and unicodedata.digit()
now return the correct value for large code points
- repr() may consider more characters as printable.
It's a ParseTuple converter: decode bytes objects to unicode using
PyUnicode_DecodeFSDefaultAndSize(); str objects are output as-is.
* Don't specify surrogateescape error handler in the comments nor the
documentation, but PyUnicode_DecodeFSDefaultAndSize() and
PyUnicode_EncodeFSDefault() because these functions use strict error handler
for the mbcs encoding (on Windows).
* Remove PyUnicode_FSConverter() comment in unicodeobject.c to avoid
inconsistency with unicodeobject.h.
