How spell names appear when cast

This seems super basic but I was not able to find an answer after searching many discussions.

I would like to remove the spell white/black/effect icon so that spell names can be one letter longer. However, as I'm sure you know, the first character in spell names is omitted when spells are used in battle.

I'm guessing a simple pointer change would remove this effect, but I'm not sure where to start. Does anybody know?

Thanks!
