We reviewed this and have decided to leave titles as text-only, *but* we have a workaround that we hope isn't too difficult.

To support HTML entities we'd have to run titles through HTML rendering, which adds an opening for security risks.  Sure, we have those with the body already, but this would be one more place where we'd have to guard against problematic inputs for an infrequent use case.  **However**, titles *do* support Unicode (demonstrated in the L&L question you linked), and post bodies support HTML entities.  If you don't happen to know the keyboard commands for the character you want, you can type the HTML entity in the post body and then cut/paste the result from the rendered preview.  (If you're using several, you might find it easier to do the entire title that way.)

I hope this workaround isn't too much of an imposition.  If there are cases where this approach really doesn't work, please let us know.
