DNS could be hosted on a blockchain, each person use his own rules for validating names, and reject, accept or rename any ambiguous or dangerous part of the name, in a totally secure and immutable way. Blockchain has the potential to be the fastest and cheapest network on the planet, because it is the only "perfect competition" system on the internet. "Perfect competition" comes from game theory, and "perfect" means that no one is excluded from competing. "Competition" means that the best performing nodes of the network put the less efficient nodes out of business. For the moment unfortunately, there is no blockchain which is the fastest network on the planet, but that's gonna change. Game theory suggests that there will be a number of steps before that happens, and it takes time. In other words, the game will have to be played for a while, for some objectives to be achieved. UTF8 and glyphs are not related to supply chains, and that's a little bit off topic, but i wanted to mention that there is a solution.
