This character is a Other Punctuation and is commonly used, that is, in no specific script. The character is also known as permyriad.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as end of a European number, e.g., a currency symbol, from left to right. When changing direction it is not mirrored. U+2031 prohibits a line break before it, if it follows a number. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
A basis point (often abbreviated as bp, often pronounced as "bip" or "beep") is one hundredth of 1 percentage point. Changes of interest rates are often stated in basis points. For example, if an existing interest rate of 10 percent is increased by 1 basis point, the new interest rate would be 10.01 percent.
The related term permyriad means one part per ten thousand.
