U+212B Angstrom Sign

U+212B was added in Unicode version 1.1 in 1993. It belongs to the block U+2100 to U+214F Letterlike Symbols in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Uppercase Letter and is mainly used in the Latin script. Its lowercase variant is Latin Small Letter A with Ring Above.

The glyph is a canonical version of the glyph Latin Capital Letter A with Ring Above. 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. If its East Asian Width is “narrow”, U+212B forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
