U+115DC "𑗜" Siddham Vowel Sign Alternate U Unicode Character

U+115DC "𑗜" Siddham Vowel Sign Alternate U is a combining diacritical mark used in the historical Siddham script to represent the vowel sound "u" as an alternative typographic form to the standard Siddham vowel sign for "u". This character is part of the Siddham block, which encodes the script employed primarily for writing Sanskrit and other languages in East Asian Buddhist contexts, notably in Japan and China. The alternate form likely appears in manuscripts or inscriptions where scribes used a different stroke style for aesthetic or calligraphic reasons, and it attaches to a preceding consonant character to modify its inherent vowel, functioning just as the primary vowel sign but with a distinct visual appearance.
