Add possibility to provide new functions like utf8 and ascii.

Some systems rely on obscure string encodings. A mechanism to provide custom formatters would be a nice feature to have. Maybe it could be based on WASM? And customasm provides a library that such formatters compile against.

One could the tell customasm to load these formatters: customasm --formatters <file>,<dir> .... Maybe this could be turned into customasm functioning more as an "engine" of some kind.

I had the intention of adding support for a charmap directive, which I've seen other assemblers do. Then you could specify a translation table for each character (or range of characters) into your specific encoding -- much like we already do with instructions in a ruledef block.

Something like this. Do you think that would be enough?

Pokemon was the example I had in mind :) I think that would be enough for this use-case, definitely!
