Display Unicode in HTML with AngularJS?

Avoid writing HTML markup from script. As soon as the data may content HTML-special characters like < and & you've got breakage and potentially security issues (XSS).

The character referred to by the HTML markup ↓ is U+2193 Downwards Arrow. You can refer to it directly in JavaScript using a JS string literal escape:

'name': '\u2193NASDAQ',

Or if your page/script is consistently saved and served in a Unicode-safe format (eg UTF-8) then you don't need to escape it at all:

'name': '↓NASDAQ',

Angular ships with Strict Contextual Escaping. So you'd have to explicitly say that you want to render some character as HTML.

Notice, I have also added ng-sanitize in the External Resources.

I created a new filter

mOverview.filter('unsafe', function($sce) {
    return function(val) {
        return $sce.trustAsHtml(val);
    };
});

and used it in view like this:

<td ng-bind-html="md.name | unsafe"></td>
