One possible solution: Add button (btn-default) near title, with clear message (go to unread message)
Have much more possible solutions? - add settings to the ACP. Every community will select most UX friendly for them.
This doesn't crash by the way it just can't decode the title at
and uses the fallback, which is either browserTitle, siteTitle or NodeBB.
