American Imperialism has absolutely resulted in some horrible things, but I hardly think that ASCII is one of them.

ASCII wasn't "imperialism," it was pragmatism. Yes, it privileged English -- but that's because the engineers designing it _spoke_ English and the US was funding + exporting most of the early computer and networking gear. The US Military essentially gave the world TCP/IP (via DARPA) for free!

Maybe "cultural dominance", but "imperialism at its worst" is a ridiculous take.
