U+1EE1 "ỡ" Latin Small Letter O with Horn and Tilde Unicode Character

U+1EE1 "ỡ" Latin Small Letter O with Horn and Tilde is a specialized character used in the Vietnamese alphabet to represent a specific vowel sound, formed by combining the base Latin letter O with a horn diacritic (a small hook added to the upper right) and a tilde diacritic above. This character is a distinct element in written Vietnamese, where the horn modifies the vowel's pronunciation to create a more central or rounded sound, while the tilde indicates a specific tonal contour, specifically the falling-rising tone. As part of the Unicode standard, it ensures consistent representation of Vietnamese text across digital platforms, preserving the language's complex diacritic system without relying on workarounds or font substitutions.
