Add line break within tooltips

Question

How can line breaks be added within a HTML tooltip?

I tried using
and \\n within the tooltip as follows:

Answer 1

The javascript version

Since (html) is 0D (hex), this can be represented as '\u000d'

str = str.replace(/\n/g, '\u000d');

In addition,

Sharing with you guys an AngularJS filter that replaces \n with that character thanks to the references in the other answers

app.filter('titleLineBreaker', function () {
    return function (str) {
        if (!str) {
            return str;
        }

        return str.replace(/\n/g, '\u000d');
    };
});
