Sidetic Value in Script Unicode Property

Sidetic is a historical script used in ancient Sidē, a city in Pamphylia (modern-day Turkey), dating from roughly the 5th to 2nd centuries BCE. In the context of text processing, the “Sidetic” value identifies characters that belong to this writing system, which consists of around 25 known signs, including vowel and consonant letters, some of which resemble Greek forms but with distinct phonetic values. This assignment helps software correctly render, sort, and analyze the sparse inscriptions left behind, often found on coins and stone monuments. The script remains only partially deciphered, and its Unicode encoding supports scholarly work by preserving these rare glyphs as distinct digital entities, enabling precise linguistic study without conflating them with other ancient alphabets.
