[TYPO3-english] gifbuilder and trademark symbols

[Simon Browning]

Is it possible to have the gifbuilder render trademark symbols (the TM 
or R)?  We're replacing one of the stdheaders with a graphic, and I've 
spent a couple of hours trying to get the symbols to show up, but can't 
seem to make it happen.

Any tips?

I'm using TYPO3 4.7.1

Thanks

Simon
