U+135E "፞" Ethiopic Combining Vowel Length Mark Unicode Character

U+135E "፞" Ethiopic Combining Vowel Length Mark is a diacritical mark used in the Ethiopic script, primarily for writing languages like Ge'ez, Amharic, and Tigrinya. It is placed above a consonant base character to indicate that the inherent or attached vowel sound should be lengthened, functioning as a phonetic modifier rather than an independent letter. This combination mark helps distinguish word meanings and grammatical forms where vowel length is significant, though its usage is less common in modern standard orthographies compared to other vowel marks.
