U+A7D3 "ꟓ" Latin Small Letter Double Thorn Unicode Character

U+A7D3 "ꟓ" Latin Small Letter Double Thorn is a relatively recent addition to the Unicode Standard, specifically encoded in version 14.0 released in September 2021. It represents a historical typographic ligature used in Early Modern English and other languages, formed by combining two instances of the letter "thorn" (þ, which itself represents the "th" sound). This character was included to support the accurate reproduction of original printed texts, where such ligatures were common in blackletter and early typeface styles. Its primary modern purpose is for scholarly work and digital archiving of historical documents, allowing researchers to faithfully transcribe and display the distinct characters used in centuries-old writings without resorting to visual approximations or separate coding combinations.
