The same changes are reflected in angband.fnt in this archive. You have to run xrdb in this case to make the change take effect.
Some variants are very straighforward to deal with, some are terribly hard.
I find modifying the program for PernAngband is nearly impossible, for example. You still can interact with visuals, but since there are way to many tarrain features, monsters and items in Pern, I attached an incomplete prf file for that.
