This character is a Other Letter and is commonly used, that is, in no specific script. The character is also known as second transfinite cardinal (the continuum).
The glyph is a compatibility version of the glyph Hebrew Letter Bet. 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+2136 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
