How to convert large UTF-8 strings into ASCII?

Question

I need to convert large UTF-8 strings into ASCII. It should be reversible, and ideally a quick/lightweight algorithm.

How can I do this? I need the source

An implementation of the quote() function might do what you want. My version can be found here

You can use eval() to reverse the encoding:

var foo = 'Hägar';
var quotedFoo = quote(foo);
var unquotedFoo = eval(quotedFoo);
alert(foo === unquotedFoo);
