U+1EDD "ờ" Latin Small Letter O with Horn and Grave Unicode Character

U+1EDD "ờ" Latin Small Letter O with Horn and Grave is a precomposed character used primarily in the Vietnamese language to represent a specific tone and vowel sound. It combines the base Latin letter O with a diacritical horn added to the top right, which creates the distinct "ơ" vowel, and a grave accent placed above it to indicate a low falling tone. This character is essential for accurately writing and pronouncing words in Vietnamese, such as "cờ" meaning "flag," and it is typically encoded using a Unicode normalization form that ensures consistent representation across digital systems.
