[html5] Validator.ru meta charset

Thu Feb 21 13:31:31 PST 2013

I've installed validator.ru on a unbuntu box using the instructions located at http://about.validator.nu/#src

When I validate a html5 document (via the text input option) with the meta tag and charset attribute I get an error:
Error: Bad value utf-8 for attribute charset on element meta: utf-8 is not a valid character encoding name.

However this doesn't occur when doing the same validation via validator.nu.

Has anyone had the same issue running validator.ru locally?

Thanks

Sample document:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<p></p>
</body>
</html>
