Service Mark in title
I think the issue is that craft will sanitise (escape) any code before it goes into the database, to prevent any code injection and twig will also do the same at a template level (to prevent script injection).

If you have your entry title as DIVA! Becomes Famous &amp;#8480 for example, it will appear like that in craft and in your templates, but if you do {{ entry.title|raw }} it will actually output ℠ in your template.

From the twig docs:


  The raw filter marks the value as being "safe", which means that in an environment with automatic escaping enabled this variable will not be escaped if raw is the last filter applied to it
