gaf

Wikipedia:

Gaf or Gāf may be the name of four different Perso-Arabic letters, all representing [ɡ]. They are all forms of the letter kāf, with additional diacritics, such as dots and lines. There are three forms, each used in different places:

Gaf with line

گ‎ is based on kāf with an additional line. It is rarely used in Arabic itself, but may be used to represent the sound [ɡ] when writing other languages. It is frequently used in Persian and Kurdish and it is one of four letters which are not found in Arabic.

Gaf with single dot

ݢ‎ is derived from a variant form (ک‎) of kāf with the addition of a dot. It is not used in the Arabic language itself, but is used in the Jawi script of Malay to represent a voiced velar stop [ɡ]. Unicode includes two forms on this letter: one based on the standard Arabic kāf, ك‎, and one based on the variant form ک‎. The latter is the preferred form.

Gaf with three dots

ݣ ‎ is based on a variant form (ک‎) of kāf with the addition of three dots. It is used in informal Moroccan Arabic to represent /ɡ/. The letter is also used officially to transliterate the voiced velar plosive as in many city names such as Agadir (أݣادير‎, also written: أغادير‎) and family names such as El Guerrouj (الݣروج‎, also written: الكروج‎).

Its initial and medial forms are identical to ڭ‎, which represents [ŋ] in some languages. However, their final and isolated forms are different.
