This character is a Uppercase Letter and is commonly used, that is, in no specific script. The character is also known as Bernoulli function.
The glyph is a font version of the glyph Glyph for U+0042Latin Capital Letter B. 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+212C forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
