About this character

U+01DE (Ǟ) is LATIN CAPITAL LETTER A WITH DIAERESIS AND MACRON, an uppercase letter in the Latin Extended-B block. It belongs to the Latin script. It was added in Unicode 1.1 (1993).

Its lowercase form is U+01DF ǟ.

It is precomposed. Under NFD it decomposes into U+0041 A + U+0308 ◌̈ + U+0304 ◌̄, and NFC recombines that sequence into this single codepoint, so both spellings are canonically equivalent and should compare equal after normalization. See the normalization guide.
