This is a task for investigation of possible issues with the arabic transliteration in Kazakh (kk) and Kurdish (ku).

Documentation of 'proper' transliteration seems to be at https://en.wikipedia.org/wiki/Kazakh_alphabets

The files implementing the transliteration are at:
https://github.com/wikimedia/mediawiki/blob/master/languages/classes/LanguageKk.php
https://github.com/wikimedia/mediawiki/blob/master/languages/classes/LanguageKu.php

Information on LanguageConverter is at https://www.mediawiki.org/wiki/LanguageConverter

One issue to be aware of is that Google Chrome seems to misrender the Kazakh arabic. Double-check renderings with Firefox, which seems to be more reliable. (Rendering issues have to do with word-initial/medial/final forms of the Kazakh-specific letters, like 06d5. The sequence 06D5 0644 renders disconnected, for instance -- perhaps it should render connected?

We could use some hand-written examples to sanity-check the renderings.
