Hi! I've got no objection to including Arabic in the set of covered
languages, but handing us a new unaccent.rules file isn't the way to
do it, because that's a generated file. The adjacent script
generate_unaccent_rules.py generates it from the official Unicode
source data (see comments in that script). What we need, ultimately,
is a patch to that script so it will emit these additional translations.
Past commits that might be useful sources of inspiration include

If you're not good with Python, maybe you could just explain to us
how to recognize these characters from Unicode character properties.
