Are fonts Turing-complete now? I have a feeling they'll become such if not already there; a little programs, complete with configuration switches so that you can control if and how a combination of characters get converted into a ligature depending on surrounding context.

TrueType font hinting actually is Turing complete. A font may contain programs that run on a VM that has functions, variables, unbounded loops, etc.
