Ṭe

Ṭe is a letter of the extended Arabic alphabet, derived from te (ت) by replacing the dots with a small t̤oʾe (ط; historically four dots in a square pattern, e.g. ٿ^[a]).^[1] It is not used in the Arabic alphabet itself, but is used to represent an voiceless retroflex plosive [ʈ] in Urdu, Punjabi written in the Shahmukhi script, and Kashmiri as well as Balochi. The small t̤oʾe diacritic 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 tā-ye-musaqqalā ("heavy te")^[1] or tā-ye-hindiyā ("Indian te"). In Devanagari, this consonant is rendered using ‘ट’.

Some layout engines do not properly generate the medial and initial forms (which should look like ـٹـ and ﭨ) and will render the isolate form ٹ, without joining.
