HTML Checking for Large Sites
Rocket Validator automatically checks your pages on the W3C Validator.
HTML issues tagged as content.
A <meta> tag has been found in the document stating that the charset is windows-1251, but it actually is utf-8. You should update the tag to reflect the actual encoding of the document, for example:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
A <meta> tag has been found in the document stating that the charset is windows-1252, but it actually is utf-8. You should update the tag to reflect the actual encoding of the document, for example:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
A <meta> element without a content, itemprop or property attributes has been found in an unexpected place.
Check its attributes and context - depending on the section of the document (<head> or <body>), the <meta> element allows different attributes.

A <meta> tag has been found that is missing its required content. Example of a valid meta tag:
<meta name="description" content="Description of the page" />
In HTML5 you’re encouraged to use Unicode (UTF-8) character encoding rather than a legacy character encoding such as Latin1 (Windows-1252 or ISO 8859-1).
In short, it can be just a matter of using <meta charset="utf-8"/> in your document, but you should also ensure that your pages are also saved and served as UTF-8.
