Mimic, the Evil Script That Will Drive Programmers To Insanity (github.com)
JustAnotherOldGuy writes: Mimic implements a devilishly sick idea floated on Twitter by Peter Ritchie: "Replace a semicolon (;) with a Greek question mark (;) in your friend's C# code and watch them pull their hair out over the syntax error." There are quite a few characters in the Unicode character set that look, to some extent or another, like others – homoglyphs. Mimic substitutes common ASCII characters for obscure homoglyphs. Caution: using this script may get you fired and/or beaten to a pulp.
Unicode in code is for people that do not understand what they are doing.
This. To me it's the same argument as keeping domain names in plain ASCII -- portability. If I cannot type a domain name on any random keyboard, then it has no place on the _inter_net. Code should be similarly universal for a number of reasons, even if it's restricted to one organization; it's like math notation.
(My native language has a few non-Latin characters and I also use Hanzi occasionally, but I like having some common ground with other people.)
