[New-bugs-announce] [issue21165] Optimize str.translate() for replacement with substrings and non-ASCII strings

[STINNER Victor]

New submission from STINNER Victor:

In issue #21118, I optimized str.translate() in Python 3.5 for ASCII 1:1 mapping and ASCII deletion. My optimization is not used if a character is replaced with a string (ex: "abc".translate({ord('a'): "xxx"})) and for non-ASCII strings.

translate_script.py is a simple benchmark for 1:1 mapping. It should be enhanced to benchmark also replacement strings.
