The 255 is not official, either.  Officially we support 127
characters, plain ASCII, because our file format is plain ASCII.

UTF-8 is the way to go.  It's backwards-compatible with ASCII.  IMHO,
at this point it's foolish to contemplate anything else.

We'd need a way to refer to an external font somehow, but then we have
the problem of PCB files no longer being idempotent.

Embedding large fonts might only be practical if we switch to a binary
format that can embed the compressed font as-is, but we'd need a way
to convert to-from text format, or use a container like zip, to work
with existing tools that want a plain text file.
