The Tai Tham block contains characters used in the Tai Tham script, which is used for writing the Northern Thai, Tai Lue, and Khün languages spoken in northern Thailand, Laos, and Myanmar. The script is an abugida, with each consonant carrying an inherent vowel sound that can be modified with diacritics. The Tai Tham script has been used primarily for religious texts, particularly in the context of Theravada Buddhism. This block includes all the necessary characters for writing in Tai Tham, reflecting its significance in the cultural and religious traditions of the Tai peoples..
