Recently, I've been thinking that domain-specific one-byte code pages are nicer than troublesome UTF-8 decoding or dealing with the atrocious mess of Unicode. See homoglyph attacks, zalgo text, ZWJ combining pictographs, etc. The only real upside I see to it is that it's nearly universally supported and allows uniformly encoded, multi-language text.
ASCII was designed at a time where combining characters were a useful hack and out-of-band communication with the teletype wasn't an option. Does anyone still use the ASCII separator, device control, or vertical tab characters for what they were designed for?
