Check for visual presence of character on page?
<p>I'm in an odd situation where I need to check, via a test, that a currency symbol is being properly displayed on our web page. </p>

<p>We've been running into issues where sometimes the unicode alphanumeric value is showing up on the page instead of the actual currency symbol itself.</p>

<p>Is there a way to check for something like this? Like with some type of visual checking library, or through javascript?</p>
