U+1ECB "ị" Latin Small Letter I with Dot Below Unicode Character

U+1ECB "ị" Latin Small Letter I with Dot Below is a precomposed character used primarily in the Vietnamese alphabet, where the dot below represents the nặng tone, a low, glottalized pitch. This character combines the base Latin letter 'i' with a combining dot below, allowing for correct digital representation of Vietnamese words such as "mị" (meaning beautiful or charming) and "thị" (meaning market or to be). It is encoded in the Latin Extended Additional block of Unicode to support proper rendering and storage of Vietnamese text, distinguishing it from sequences that might use a separate combining mark.
