U+1E8A "Ẋ" Latin Capital Letter X with Dot Above Unicode Character
U+1E8A "Ẋ" Latin Capital Letter X with Dot Above is a specialized typographic symbol used in certain Latin-based orthographies, most notably in the Chechen Latin alphabet created in the 1990s and occasionally in transliteration systems such as those for Semitic languages, where it often represents a voiced velar fricative or a pharyngealized sound similar to the Arabic letter Ghain. The dot placed above the standard capital X modifies its phonetic value, distinguishing it from the plain X in writing systems that require precise representation of specific consonants. This character belongs to the Latin Extended Additional block in Unicode and is encoded for digital text to support minority languages and academic transcription, ensuring that users can accurately display and process this distinct letter across modern software and platforms.
