I can’t find anything that says a question mark isn’t legitimate.
No reason why not - any characters within the charset you’ve defined can be used, and character entities should be used for any others (including " if you need it).
content CDATA #REQUIRED – associated information –
CDATA is a sequence of characters from the document character set and may include character entities. User agents should interpret attribute values as follows:
Replace character entities with characters,
Ignore line feeds,
Replace each carriage return or tab with a single space.
CDATA is the same as normal content text in html – so anything you can use on your content you can put into your CONTENT attribute.
