Warnings:
The character encoding “windows-31j” is not widely supported. Better interoperability may be achieved by using “UTF-8”.
Attribute with the local name “xmlns:og” is not serializable as XML 1.0.
Attribute with the local name “xmlns:fb” is not serializable as XML 1.0.
The “charset” attribute on the “script” element is obsolete.
The “type” attribute is unnecessary for JavaScript resources.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Errors:
Legacy encoding “windows-31j” used. Documents must use UTF-8.
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
Attribute “xmlns:og” not allowed here.
Attribute “xmlns:fb” not allowed here.
Internal encoding declaration “shift_jis” disagrees with the actual encoding of the document (“windows-31j”).
Bad value “text/html; charset=Shift_JIS” for attribute “content” on element “meta”: “charset=” must be followed by “utf-8”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
The only allowed value for the “charset” attribute for the “script” element is “utf-8”. (But the attribute is not needed and should be omitted altogether.)
Bad value “handheld” for attribute “media” on element “link”: Deprecated media type “handheld”. For guidance, see the Media Types section in the current Media Queries specification.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “modulepreload”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
