HTML-validator på w3c.org säger följande:
I was not able to extract a character encoding labeling from any of the valid sources for such information. Without encoding information it is impossible to reliably validate the document. I'm falling back to the "UTF-8" encoding and will attempt to perform the validation, but this is likely to fail for all non-trivial documents.
Sorry, I am unable to validate this document because on line 73, 79-82, 84-85, 87, 89-90, 92-95, 97, 99, 101, 103, 105-110, 112, 127, 156-158 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.
