U+0EC2 "ໂ" Lao Vowel Sign O Unicode Character

U+0EC2 "ໂ" Lao Vowel Sign O is a combining mark used in the Lao script to represent the long vowel sound /oː/, similar to the "o" in the English word "go". This vowel sign is placed before the consonant it modifies, rather than above or below it, making it one of the few preposed vowel symbols in the Lao writing system. It is an essential component in the correct spelling of many Lao words, and its distinct visual form, resembling a small open circle or hook attached to a short line, differs markedly from the vowel signs of related scripts like Thai.
