Hello there! I am working on localizing numerical values in some Wikimedia applications (XTools[0], namely). I've been using PHP's NumberFormatter[1] and it works great for some languages like Arabic and Persian.

However Kurdish, specifically ckb (as in ckb.wikipedia.org[2]), is apparently missing from this PHP library. I've searched the whole internet over, and can't figure out how I am meant to install it. Evidently it boils down to what languages are installed on your machine, which I think under a Unix-like system is "locale -a". Indeed I don't see ckb or any of the other Kurdish variants like ku, kur, kmr, and sdh. The same is true when I run this command on Toolfroge/VPS, where my tools are hosted.

Knowing that Kurdish Wikipedia[2] is a thing, and that MediaWiki is built in PHP, I was hoping someone here would know what needs to be done to support Kurdish in my application? I have all the Kurdish message translations, via translatewiki, I just need to localize the numerical values using the standard PHP NumberFormatter.
