U+0391 Greek Capital Letter Alpha

U+0391 was added in Unicode version 1.1 in 1993. It belongs to the block U+0370 to U+03FF Greek and Coptic in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Uppercase Letter and is mainly used in the Greek script. Its lowercase variant is Glyph for U+03B1 Greek Small Letter Alpha.

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+0391 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
