U+115D9 "𑗙" Siddham Letter Two-Circle Alternate I Unicode Character

U+115D9 "𑗙" Siddham Letter Two-Circle Alternate I is a special vowel sign used in the Siddham script, an historic Brahmic writing system primarily employed for Buddhist texts and mantras in East Asia, particularly in Japan. This character represents an alternate graphical form of the vowel "I," distinguished by its unique two-circle design, which differs from the standard representation found in the Siddham inventory. As a typographic variant, it was likely developed in manuscript traditions to provide visual distinctiveness or to fit specific calligraphic styles, and its inclusion in Unicode allows for accurate digital representation of historical Siddham documents.
