Ṭē is an additional letter of the Perso-Arabic alphabet, derived from te (ت) by replacing the dots with a small t̤oʾe (ط). It is not used in the Arabic alphabet itself, but is used to represent [ʈ] in Urdu. The small t̤oʾe diactric is used to indicate a retroflex consonant in Urdu. It is the fifth letter of the Urdu alphabet. Its Abjad value is considered to be 400. In Urdu, this letter may also be called ‘heavy t’ or ‘Indian t’. In Devanagari, this consonant is rendered using ‘ट’.
Position in word:
Some layout engines do not properly generate medial and final forms (which should look like ـٹـ and ﭨ) and will render the isolate form ٹ, without joining.
