punycode
punycode is so cool. It's esoteric, but like, it's amazing what ingenuity can do.
It's an encoding of UTF-8 - the kind of text with easy representations for unicode sequences like ñ - in ASCII - the one that just supports English. It does this in a way that's reversible, and lets us use UTF8 text in ASCII places, because you can also detect when something is written in punycode. Do you need this, probably not – but someday you will, and you will remember.
