Its appearance is "W" (the first letter of "Won") with a horizontal strike going through the center. Some fonts display the won sign with two horizontal lines, and others with only one horizontal line. Both forms are used when handwritten.
Encoding
The Unicode code point is U+20A9₩WON SIGN: this is valid for either appearance. Additionally, there is a fullwidth character at U+FFE6₩FULLWIDTH WON SIGN (in the block halfwidth and fullwidth forms).
In Korean versions of Windows, many fonts (including system fonts) display the backslash character as the won sign. This also applies to the directory separator character (for example, C:₩Program Files₩) and the escape character (₩n). Most Korean keyboards input 0x5C when the won sign key is pressed,[dubious – discuss] so the Unicode letters are rarely used.[clarification needed]
The same issue (of dual use of a code point) occurs with the yen sign in Japanese versions of Windows.
MacOS
In macOS, the won sign key inputs U+20A9₩WON SIGN only when in Hangul input mode.
