Ꝼ
U+A77B "Ꝼ" Latin Capital Letter Insular F is a historical typographic form of the letter F, primarily used in medieval manuscripts written in Old English and other early Insular scripts such as Irish and Scottish Gaelic. Unlike the standard Latin F, the Insular F features an extended ascender and a more open, rounded top stroke, reflecting the distinct calligraphic style of the British Isles. This character was introduced into Unicode to support the accurate digitization of ancient texts, where it often represents the same phoneme as a regular F but with a specific scribal appearance. Its lowercase counterpart, U+A77C "ꝼ" Latin Small Letter Insular F, is also encoded for completeness in scholarly and historical typography.
