U+17D1 "៑" Khmer Sign Viriam Unicode Character
Unicode Version 17.0
៑
U+17D1 "៑" Khmer Sign Viriam is a diacritical mark used in the Khmer script, primarily in older or liturgical texts, to indicate that a final consonant should be pronounced without its inherent vowel, effectively making it a dead consonant or adding a subtle aspirated or breathy quality to the syllable’s ending. It appears above the consonant and is distinct from the more common Khmer subscript consonant forms, often serving as a phonetic guide for reading Pali and Sanskrit loanwords in religious or classical contexts. While rarely used in modern standard Khmer, the viriam preserves historical pronunciation patterns and is an essential part of the script’s orthographic system for transcribing ancient texts.
