Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as content-type.
In order to define the charset encoding of an HTML document, both of these options are valid, but only one of them must appear in the document:
<!-- This is the preferred way --> <meta charset="UTF-8"> <!-- This is the older way, also valid --> <meta http-equiv="content-type" content="text/html; charset=UTF-8">
