Che or cheem (چ) is a letter of the Persian alphabet, used to represent [t͡ʃ], and which derives from ǧīm (ج) by the addition of two dots.
It is used in Persian, Urdu, Pashto, Kurdish, Uyghur, Kashmiri, Azerbaijani, Ottoman Turkish, Malay (Jawi), Javanese (Pegon), and other Indo-Iranian languages.
When representing this sound in transliteration of Persian into Hebrew, it is written as ג׳ gimel and a geresh.
Since the sound is not part of Standard Arabic’s phonology; In most of the rest of Arabic-speaking geographic regions, the combination of tāʾ-šīn (تش) is more likely used to transliterate the /t͡ʃ/ sound which is often realized as two consonants ([t]+[ʃ]) as in "تشاد" /tʃaːd/ (Chad) and "التشيك" /at.tʃiːk/ (Czech Republic).
The /ʒ/ pronunciation is also proposed for South Arabian minority languages, like Mehri and Soqotri.
