another good one to sneak in there... thai zero-width space: U+200B

cant see it, nothing reads it, and it makes everything error. : D

Pretty much any ide will spot that. Maybe you can use it to teach your colleagues not to use a plain text editor.

fr*cking rust ruining the fun

Okay fuck you op

IDE users pretending compilers don't exist.

$ guix shell gcc

[env]$ g++ test.cpp 
test.cpp:4:16: warning: `0;' is not in NFC [-Wnormalized=]
    4 |         return 0<U+037E>
      |                ^~~~~~~~~
test.cpp: In function ‘int main()’:
test.cpp:4:16: error: unable to find numeric literal operator ‘operator"";’
test.cpp:4:18: error: expected ‘;’ before ‘}’ token
    4 |         return 0;
      |                  ^
      |                  ;
    5 | }
      | ~

Look ma, no IDE! 😸

This is indeed some next-level fuckery.

I don't see a problem

#include <iostream>

#define ; ;;

int main(){
  std::cout << ";\n";
}

Any half-decent editor/IDE/command line tool will scream at you about this; plus there's version control which should help you spot it as well.

With the "wonderful" tooling at work, we use Skype for Business. Naturally, that is not the primary place to send around code and configs, but a 1-liner or 2-liner happens.

You can't believe the nonsense it does when you try to copy & paste it. Spaces get turned into non-breaking spaces etc. Looks completely normal when pasted directly into vim on a console, but will give "odd" error messages.

There is no wise way to use that information.

But the foolish ones could be entertaining.

Wow!

This seems to be further evidence that the process for assigning UTF entities has been thoroughly corrupted.

You can (apparently) copy/paste this on mobile:

";" (Greek question mark)

";" (Semicolon)

You can even render it in HTML:

    ;
    ;

And it's included on Wikipedia, because of course it is:

• https://en.wikipedia.org/wiki/Question_mark

Because I'm not sure what my mobile client will actually do with this comment, here's the link to the HTML entity I used:

• https://www.compart.com/en/unicode/U+037E

Also there's plenty of other character joy to be had:

What exactly do you think you can do with this?

Remember .. with great power comes .. something.
