[ab]using Unicode to create tragedy

Introduction

monster

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 (;) 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 – homoglyphs. Mimic substitutes common ASCII characters for obscure homoglyphs.

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

Results

Observe the mayhem:

some bad code "BUT WHY?"

Or, if you've been mimicked a little harder,

some worse code
