69f92ebaec [3.11] gh-155292: Don't consider Unicode codepoint attributes outside RFC 3454 (GH-155293) (GH-156020) (#156931)
* [3.11] gh-155292: Don't consider Unicode codepoint attributes outside RFC 3454 (GH-155293) (GH-156020)

Due to a bug, some Unicode codepoint attributes were considered
for characters not yet defined in Unicode 3.2.0 or attributes
which changed in later Unicode versions. RFC 3454 (StringPrep)
requires using Unicode 3.2.0 strictly.

(cherry picked from commit 7e109d084d)
The cherry-pick needed reworking as GH-144815 wasn't backported to 3.14
and below, so unassigned characters don't have bidi values.
