In Unicode, the majuscule Ƣ is encoded in the Latin Extended-B block at U+01A2 and the minuscule ƣ is encoded at U+01A3. The assigned names, "LATIN CAPITAL LETTER OI" and "LATIN SMALL LETTER OI" respectively, are acknowledged by the Unicode Consortium to be mistakes, as gha is unrelated to the letters O and I. The Unicode Consortium therefore has provided the character name aliases "LATIN CAPITAL LETTER GHA" and "LATIN SMALL LETTER GHA".
