This character is a Other Punctuation and is commonly used, that is, in no specific script.
The glyph is a wide version of the glyph Percent Sign. Accordingly, its width in East Asian Text is fullwidth. 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+FF05 prohibits a line break before it, if it follows a number.
The Wikipedia has the following information about this codepoint:
The percent sign% (sometimes per cent sign in British English) is the symbol used to indicate a percentage, a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign ‰ and the permyriad (per ten thousand) sign ‱ (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand, respectively. Higher proportions use parts-per notation.
