…ythonGH-143076) Add the unicodedata.iter_graphemes() function to iterate over grapheme clusters according to rules defined in Unicode Standard Annex #29. Add unicodedata.grapheme_cluster_break(), unicodedata.indic_conjunct_break() and unicodedata.extended_pictographic() functions to get the properties of the character which are related to the above algorithm.

This is an alternative proposal for #148218. This would also require updating testpython.net with the file for UCD 16. Due to this, the network test currently fails. |

I don't think that it's a good idea to backport so much code in a stable branch. I don't think that fixing the issue in Python 3.14 is important enough to justify this backport. Python had this bug for many years. |
