This character is a Currency Symbol and is commonly used, that is, in no specific script.
The glyph is a wide version of the glyph Yen 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+FFE5 prohibits a line break after it, if it is followed by a number.
The Wikipedia has the following information about this codepoint:
The yen and yuan sign (¥) is a currency sign used for the Japanese yen and the Chinese yuan currencies when writing in Latin scripts. This character resembles a capital letter Y with a single or double horizontal stroke. The symbol is usually placed before the value it represents, for example: ¥50, or JP¥50 and CN¥50 when disambiguation is needed. When writing in Japanese and Chinese, the Japanese kanji and Chinese character is written following the amount, for example 50円 in Japan, and 50元 or 50圆 in China.
