Sorry, something went wrong.
…utside RFC 3454 (pythonGH-155293) (pythonGH-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 7e109d0) The cherry-pick needed reworking as pythonGH-144815 wasn't backported to 3.14 and below, so unassigned characters don't have bidi values. (cherry picked from commit 1e54caa) Co-authored-by: Petr Viktorin <encukou@gmail.com> Co-authored-by: Seth Larson <seth@python.org> Co-authored-by: Stan Ulbrych <89152624+stanfromireland@users.noreply.github.com> Co-authored-by: Petr Viktorin <encukou@gmail.com>
