RuneScribe has the fonts already included, but if you want to use Runic fonts on your own device, than you need you need support for the Unicode range 16A0-16FF (part of Unicode 3.0). Two fonts wich support this range are the Hnias Rune Font set created by Lars Törnqvist and the Noto Sans Runic font created by Google.
