javascript - Find and replace specific text characters across a document with JS

Question

I'm wondering if there is a lightweight way I could use JavaScript or jQuery to sniff out a specific text character across a document; say € and find all instances of this character. And then! Write an ability to replace all instances of this with say a $.

I found this snippet for starters:

var str = 'test: '';

str = str.replace(/'/g, "'");

Essentially; I am wanting a solution for a one page document. Grab all instances of X and make it XY. Only text characters.

How about this, replacing @ with $:

$("body").children().each(function () {
    $(this).html( $(this).html().replace(/@/g,"$") );
});
