Converting unicode character to string format

Question

Does anyone know how to convert a unicode to a string in javascript. For instance:

\\u2211 -> ∑ \\u0032 -> 2 \\u222B -> ∫

Answer 1

To convert an given Unicode-Char like  to String-Representation, you can also use this one-liner:

var unicodeToStr = ''.codePointAt(0).toString(16)

The above example gives you 'F21D'. Used with fontAwesome, you get street-view Icon: '\F21D'
