The glyph is a canonical composition of the glyphs Glyph for U+0041Latin Capital Letter A, Glyph for U+0307Combining Dot Above. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+0226 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
Ȧ (minuscule: ȧ) is a letter of the Latin alphabet, derived from A with the addition of a dot above the letter. It is occasionally used as a phonetic symbol for a low central vowel, /ä/. As a character in a computer file, it can be represented in the Unicode character encoding but not the standard ASCII character encoding. It was used in Harari romanization for a voiced pharyngeal fricative.
