U+178D "ឍ" Khmer Letter Ttho Unicode Character

Unicode Version 17.0

U+178D "ឍ" Khmer Letter Ttho is a character in the Khmer script used to write the Khmer language of Cambodia, representing the aspirated voiceless retroflex stop sound. It belongs to the category of consonant letters within the Khmer alphabet, which is an abugida where each character inherently includes a vowel sound, typically the short vowel /ɑː/ when no other vowel mark is attached. This particular letter is part of a series of retroflex consonants, a class that was historically influenced by Indic scripts like Pali and Sanskrit, and it is less common in modern Khmer usage, often appearing in loanwords or formal texts. In Unicode, it is encoded in the Khmer block (U+1780 to U+17FF) and contributes to the comprehensive representation of the Khmer writing system for digital text processing.
