New submission from Julian Berman <julian+python....@grayvines.com>:
This line (which contains a non-ASCII digit):
python3.9 -c "import datetime; datetime.date.fromisoformat('1963-06-1৪')"
raises:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ValueError: Invalid isoformat string: '1963-06-1৪'
under the C implementation of the datetime module, but when the pure Python
implementation is the one imported, succeeds (and produces `datetime.date(1963,
6, 14)`)
The pure Python implementation should instead explicitly check and raise when
encountering a non-ASCII string.
(On PyPy, which always uses the pure-Python implementation, this contributes to
a behavioral difference)
