U+A7D2 "꟒" Latin Capital Letter Double Thorn Unicode Character

U+A7D2 "꟒" Latin Capital Letter Double Thorn is a relatively rare addition to the Unicode Standard, intended for historical and linguistic notation rather than modern everyday use. This character represents a doubled or geminated form of the letter thorn (Þ), which itself was used in Old English and other early Germanic languages to denote the "th" sound. The double thorn likely appeared in medieval manuscripts as a scribal abbreviation for the word "that" or to express other contractions, and its inclusion in Unicode helps scholars accurately encode and reproduce primary historical texts without needing to resort to workarounds or approximations.
