Wow...
There are hundreds of fonts you can use for free.

In the context of our wonderful hobby - my guess would be a specific font that is fan created to represent (for example) dwarven runes or giant language. While I won't say it's impossible so far every one of those I've come across are free.
I appreciate the caution guys but if we are going to jump on the bandwagon I remind everyone here that any copy/paste from a PDF is unauthorized by every single license I've seen (even very permissive ones) - so that'd be illegal along with displaying that content via say a web viewer or other medium. Ditto for art taken from almost any web source...
*cough*
Just saying...
