Kidding, I actually can't remember how I initially did it (I think there is some way to make Anglo-Saxon letters with a regular keyboard, not entirely sure though), and since I've forgotten I just copy and paste my name from a previous comment or something whenever I log in. FR seems to support it well enough, although my name turns wonky looking when people reply to me.
I had to look up the translation...it’s from the Wanderer. (or more recently Cornwell). Neat.
