U+115DA "𑗚" Siddham Letter Two-Circle Alternate Ii Unicode Character

U+115DA "𑗚" Siddham Letter Two-Circle Alternate Ii is a unique glyph within the Siddham script, an ancient Brahmic writing system historically used in India and East Asia for writing Sanskrit and mantras, particularly in Buddhist contexts. This character represents an alternate form of the vowel "Ii," distinguished by its distinctive two-circle design that visually sets it apart from the standard Siddham letter for the same sound. It appears in the Siddham Supplement block of Unicode and serves as a specialist typographical variant, likely employed in ritual or calligraphic texts where stylistic or sectarian preferences demanded a different graphical representation of the long i vowel.
