Can you provide a link to community consensus?

Oh wait, Levantine Arabic Wikipedia (apc) is still in the Incubator. I am not sure if this possible

Levantine Arabic's Wikipedia doesn't have a big community. But the two most-active editors have requested the change.

User:HitomiAkane said this on https://discord.gg/5jKcDQJkcu:

قتراح:
نستخدم الأرقام العربية (1 2 3 4 5 6 7 8 9 0) بدل الهندية (۰ ۱ ۲ ۳ ٤ ٥ ٦ ٧ ۸ ۹)

Suggestion:
We use Arabic numerals (1 2 3 4 5 6 7 8 9 0) instead of Easter Arabic numerals (٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩). (translation mine)

And I agree. It was what I requested to begin with when the translation interface was being set up a few months ago (https://translatewiki.net/wiki/User_talk:FunLater) but this isn't what ended up happening.

Here's the on-wiki discussion: https://incubator.wikimedia.org/wiki/Wp/apc/%D9%88%D9%8A%D9%83%D9%8A%D8%A8%D9%8A%D8%AF%D9%8A%D8%A7:%D9%86%D9%82%D8%A7%D8%B4_%D8%A7%D9%84%D9%85%D8%AC%D8%AA%D9%85%D8%B9/%D9%84%D8%BA%D8%A9#%D9%86%D8%B8%D8%A7%D9%85_%D8%A7%D9%84%D8%AA%D8%B1%D9%82%D9%8A%D9%85_(%D8%A7%D9%84%D8%A3%D8%B1%D9%82%D8%A7%D9%85)

We moved the discussion to the local village pump

Thank you for tagging this task with good first task for Wikimedia newcomers!

Newcomers often may not be aware of things that may seem obvious to seasoned contributors, so please take a moment to reflect on how this task might look to somebody who has never contributed to Wikimedia projects.

A good first task is a self-contained, non-controversial task with a clear approach. It should be well-described with pointers to help a completely new contributor, for example it should clearly pointed to the codebase URL and provide clear steps to help a contributor get setup for success. We've included some guidelines at https://phabricator.wikimedia.org/tag/good_first_task/ !

Thank you for helping us drive new contributions to our projects <3

It looks like PHP is helpfully converting the number to arabic itself, which means that the digitTransformTable in MessageApc.php isn't doing anything:

$digitTransformTable = [
	'0' => '0',
	'1' => '1',
	'2' => '2',
	'3' => '3',
	'4' => '4',
	'5' => '5',
	'6' => '6',
	'7' => '7',
	'8' => '8',
	'9' => '9',
];

Looks like the tests were a good idea! And Thanks to @cscott for finding a solution that actually works.
