[docs] [issue10665] Update and expand unicodedata module documentation

[Martin v. Löwis]

Martin v. Löwis <martin at v.loewis.de> added the comment:

Please, one issue per report and checkin, and no work-in-progress on the tracker. The issue of factually correcting claims about the unicodedata module and elaborations on how it works are unrelated issues.
