The parent post has a "چ" or "cheem" character, which is neither Arabic nor required in this case. That character is used in Persian, Urdu, Pashto, etc., but not in Arabic.

A more phonetic transliteration of "Arabic is a Semitic language, Turkish and the other Turkic languages are not" is:

أَرَبِكْ ازْ أَ سِمِتِكْ لانجوِج، تِركِشْ أَندْ اُذَرّ تُركِكْ لانجوِجزّ أَرْ نَتْ
