[ab]using Unicode to create tragedy
mimic provokes:
- fun
- frustration
- curiosity
- murderous rage
It's inspired by this terrible idea floating around:
MT: Replace a semicolon (;) with a greek question mark (อพ) in your friend's C# code and watch them pull their hair out over the syntax error

There are many more characters in the Unicode character set that look, to some extent or another, like others - homographs. Mimic substitutes common ASCII characters for obscure homographs.
Fun games to play with mimic:
- Pipe some source code through and see if you can find all of the problems
- Pipe someone else's source code through without telling them
- Be fired, and then killed
./mimic --list # Show all of the homographs
./mimic --explain=o # What crazy things can we do with this letter?
./mimic --me-harder 100 # Type some lines in and mess with every single char
./mimic --reverse # Undo the mayhem. Boooring.
cat mimic | ./mimic # Pipe the source through itself at 1%
# Turn up the knob and save the results
cat mimic | ./mimic --me-harder 25 > mimicked
# Or, if your code acts strange, but you have seen this prank before:
cat mimicked | ./mimic --reverse > unmimicked
diff unmimicked mimic
Observe the mayhem:
Or, if you've been mimicked a little harder,
