Research direction
Start by running unicode-ascii-space.py to reproduce the reported differences between Unicode and ASCII regular-expression classes. Read the linked issue discussion and identify the expected behavior before locating the relevant CPython regular-expression implementation and tests. Done means the agreed behavior is consistent for the reported ASCII space characters and covered by regression tests.
