Unicode Version 17.0
ṯ
U+1E6F "ṯ" Latin Small Letter T with Line Below is a modified letter used in certain transliteration systems and orthographies to represent a specific phonetic sound, typically a voiceless dental or alveolar plosive that is articulated with the tongue against the teeth, often indicating emphasis or a distinct consonant in languages such as Arabic or Berber transliteration. The diacritic line beneath the base letter "t" signals a specialized pronunciation, differentiating it from the standard "t" sound in linguistic notation or romanization contexts. This character is part of the Latin Extended Additional block in Unicode, designed to support scholarly and academic transcription of non-Latin scripts into Latin characters.
