U+17CD "៍" Khmer Sign Toandakhiat Unicode Character

U+17CD "៍" Khmer Sign Toandakhiat is a diacritical mark used in the Khmer script, primarily to indicate that a letter or syllable should be omitted or suppressed in pronunciation, effectively functioning as a cancellation or mute sign. It is typically placed above a consonant or vowel character to denote that the marked element is not to be spoken, often appearing in loanwords, poetic contexts, or specific lexical forms where silent letters occur. This sign plays a pragmatic role in Khmer orthography by clarifying the intended spoken form of written text, ensuring correct reading and pronunciation despite the presence of historically written letters.
