U+FFE1 Fullwidth Pound Sign

U+FFE1 was added in Unicode version 1.1 in 1993. It belongs to the block U+FF00 to U+FFEF Halfwidth and Fullwidth Forms in the U+0000 to U+FFFF Basic Multilingual Plane.

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 Pound 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+FFE1 prohibits a line break after it, if it is followed by a number.

The Wikipedia has the following information about this codepoint:

The pound sign (£) is the symbol for the pound unit of sterling – the currency of the United Kingdom and its associated Crown Dependencies and British Overseas Territories and previously of Great Britain and of the Kingdom of England. The same symbol is used for other currencies called pound, such as the Egyptian and Syrian pounds. The sign may be drawn with one or two bars depending on personal preference, but the Bank of England has used the one-bar style exclusively on banknotes since 1975.
In the United States, "pound sign" refers to the symbol # (number sign). In Canada ”pound sign” can mean £ or #.
