U+1921 "ᤡ" Limbu Vowel Sign I Unicode Character

U+1921 "ᤡ" Limbu Vowel Sign I is a diacritical mark used in the Limbu script, which is employed to write the Limbu language spoken primarily in Nepal, Sikkim, and parts of West Bengal. As a vowel sign, it represents the sound /i/ and is specifically attached to a consonant character to modify its inherent vowel, indicating a long or short 'i' sound depending on context. Unlike independent vowel letters, this combining mark appears above or to the left of the base consonant, altering the syllable's pronunciation in Limbu orthography. Its inclusion in the Unicode standard ensures that digital text can accurately represent this phoneme, supporting the preservation and modern usage of the Limbu language.
