U+1EDB "ớ" Latin Small Letter O with Horn and Acute Unicode Character

U+1EDB "ớ" Latin Small Letter O with Horn and Acute is a precomposed letter used in the Vietnamese alphabet, where it represents a specific tonal variant of the vowel sound /ɔ/. The character combines a base Latin letter O with a horn diacritic (a small hook attached to the upper right side, typical for Vietnamese) and an acute accent (´) placed above it, which indicates a rising tone. This letter appears in words such as "bớt" (meaning to reduce or to lessen) and is an essential component of the Vietnamese writing system, as the language relies on diacritics to distinguish both vowel sounds and tones.
