Latin script in Unicode

Over a thousand characters from the Latin script are encoded in the Unicode Standard, grouped in several basic and extended Latin blocks. The extended ranges contain mainly precomposed letters plus diacritics that are equivalently encoded with combining diacritics, as well as some ligatures and distinct letters, used for example in the orthographies of various African languages (including click symbols in Latin Extended-B) and the Vietnamese alphabet (Latin Extended Additional). Latin Extended-C contains additions for Uighur and the Claudian letters. Latin Extended-D comprises miscellaneous characters, of which Medievalist characters are a prominent category. Latin Extended-E mostly comprises characters used for German dialectology (Teuthonista). Latin Extended-F and -G contain characters for phonetic transcription. Precomposed letters with diacritics were only included when extant in standards predating Unicode, for facilitating conversion. Letters with diacritics not found in Unicode, e.g. some letters in DIN 91379, are no longer eligible for encoding, and can only be represented as sequences of base letters and Combining Diacritical Marks.
