Moroccan Arabic (ary) could be written in Latin or Arabic alphabet.
Currently, the code is used as is, showing a real split use of the two alphabets:
MediaWiki messages translation | latin |
Commons media files description | arabic |
Incubator Wikipedia project | both |
ULS | latin |
https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/scripts_and_languages.html notes the script as arabic.
This tracking bug will track issues we have to take to offer ary speakers the possibility to use the two alphabets.
