U+1E1E "Ḟ" Latin Capital Letter F with Dot Above Unicode Character

U+1E1E "Ḟ" Latin Capital Letter F with Dot Above is a specialized grapheme used primarily in historical or linguistic orthographies, most notably in the pre-1976 spelling of Irish Gaelic to represent a lenited "f" sound, where the dot above (a diacritic known as a "ponc séimhithe") indicates a change in pronunciation or grammatical mutation. While not common in modern standard text, it remains part of the Latin Extended Additional block and is utilized in scholarly contexts, such as transcription of Old Irish or other medieval manuscripts. The character combines a standard capital F with a combining dot above, distinguishing it from the similar but lowercase character U+1E1F "ḟ".
