How to Find HTML-Encoded Character in JavaScript String?

Question

How would you go about finding a string constant that is not HTML-safe?

It appears the following searches for the individual characters.

var i = text.indexOf('&raquo;')

@Jcubed: My question includes an example of the type of character I had in mind. At any rate, the question has been asked and answered. — Jonathan Wood

You'll first need to unescape the HTML in the pattern:

var i = text.indexOf(decodeHTML('&raquo;'));

function decodeHTML(s) { // e.g. using jQuery
    return $('<div>' + s + '</div>').text();
}

var i = text.indexOf('\273')

would search for the actual character.

Try looking at the html directly.

document.getElementById('search').innerHTML.indexOf('»')

It's not able to find that. The data is updated via AJAX. Perhaps the HTML contains the character directory without using »?
