The short answer is :

/[\$\xA2-\xA5\u058F\u060B\u09F2\u09F3\u09FB\u0AF1\u0BF9\u0E3F\u17DB\u20A0-\u20BD\uA838\uFDFC\uFE69\uFF04\uFFE0\uFFE1\uFFE5\uFFE6]/

Long answer :

JavaScript regex equivalent /\p{Sc}/

is:

ScRe = /[\$\xA2-\xA5\u058F\u060B\u09F2\u09F3\u09FB\u0AF1\u0BF9\u0E3F\u17DB\u20A0-\u20BD\uA838\uFDFC\uFE69\uFF04\uFFE0\uFFE1\uFFE5\uFFE6]/

ScRe.test("$"); // true
ScRe.test("£"); // true
ScRe.test("€"); // true

\p{Sc}

is a PCRE regex property and Javascript doesn't support it.

In Javascript, you need to use specific characters in a character class to match like this:

/[$£]/
