U+17C6 "ំ" Khmer Sign Nikahit Unicode Character

U+17C6 "ំ" Khmer Sign Nikahit is a diacritical mark used in the Khmer script to represent a final nasal sound, often transliterated as an anusvara, which modifies a preceding vowel by adding a nasalized ending. It appears as a small circle or dot placed above a consonant or vowel sign, and it is distinct from the similar-looking but different-functioning Khmer Sign Toandakhiat. This mark is integral to the correct pronunciation and spelling of many words in the Khmer language, particularly in loanwords from Pali and Sanskrit, where it indicates a homorganic nasal stop.
