U+AB30 "ꬰ" Latin Small Letter Barred Alpha Unicode Character

U+AB30 "ꬰ" Latin Small Letter Barred Alpha is a typographic variant of the Latin letter alpha, originally used in certain phonetic transcription systems, most notably in the work of the early 20th-century linguist Kenneth L. Pike for the representation of sounds in unwritten languages. It features a horizontal bar through the center of the character, distinguishing it from the standard Latin alpha, and was designed to denote a specific vowel quality, typically a close-mid central unrounded vowel or a similar sound in phonetic notation. This character is part of the Latin Extended-D block, which was added to the Unicode Standard to support a range of historical and scholarly phonetic symbols that were not covered by earlier encoding.
