U+A4EF "ꓯ" Lisu Letter Ae Unicode Character

U+A4EF "ꓯ" Lisu Letter Ae is a component of the Lisu script, also known as the Fraser alphabet, which was developed in the early 20th century by missionary James O. Fraser for writing the Lisu language spoken by the Lisu people primarily in southwestern China, Myanmar, and Thailand. This character represents the sound of a long mid-central vowel, similar to the "a" in "father" or the "e" in "her" in some English dialects, and it is used to distinguish lexical and tonal meanings in the tonal Lisu language. While its glyph resembles the Latin capital letter "A" turned upside down, it is not directly related to the Latin alphabet, and it occupies a specific place in the Lisu syllabic writing system, which employs uppercase and lowercase letterforms.
