I used to work as web developer and did the same part of the project for several decades: Making sure that our Scandinavian characters åäöÅÄÖ... will work. It was feasible and it did work, basically setting everything to utf-8.
Now I wonder if it's feasible or has already been done to make sure in hardware, perhaps design a microchip, that can never do worse than making åäöÅÄÖ work? What measures would I have to take if it's feasible? If it can't be done, why is it not possible? Would I have to omit ASCII compatibility? Can I design such a chip with my development environment Altera Quartus II + some FPGA running a primitive OS?
