U+0E29 "ษ" Thai Character so Rusi Unicode Character

U+0E29 "ษ" Thai Character so Rusi is the thirty-ninth letter of the Thai alphabet, classified as a high-class consonant that represents the sound [s] at the beginning of a syllable and is considered an unaspirated sibilant. This character is used primarily in words of Sanskrit or Pali origin, where it corresponds to the retroflex sibilant śa in Devanagari, and it rarely appears in native Thai vocabulary except in formal or literary contexts. In the Thai writing system, it resides in the fourth row of the alphabet, grouped with the other high-class consonants, and its name "so rusi" translates to "the ascetic's s," referencing its historical association with a rishi in the traditional mnemonic.
