The version shown on the left is U+06BA, which is used only at the end of words. When it is used in the middle of a word it is a diacritic U+0658, which is usually omitted (see below for further information on diacritic omission in Urdu).
Sometimes choṭī hē is used to refer to hey but choṭī hē can also refer to the Arabic / Persian variant, a stylistic variation representing an equivalent letter, but Persian and Arabic usually use U+0647 whereas Urdu uses U+06C1 for gōl hey.[12] See also: Urdu in Unicode.
Most vowel diacritics are omitted in most Urdu writing, but Urdu writing usually does distinguish alif mad, and include hamza over bari ye, gol he, and wow. For example, alif mad and bare alif in آزادی - "āzādī", ɑ:zɑ:d̪i, freedom [15] - are distinguished in most contexts.
