How to change the .Title format

I have reason to believe that the leading ‘#’ in an issue HTML title block is causing some trouble with a tool I’m cut’n’pasting into (capacities). I see the head.tmpl uses the .Title macro (for lack of a better term) - how can I change the language or formatting of .Title? If I can’t without changing code, that’s fine, but I’m generally curious if it’s possible to change these entities.
