When you write a regexp to detect liquids in your cereal, you have to account for the pickles, that is, newlines an tabs.

Don't forget about the pickled cabbage (vertical tabs) and pickled pigs foot (null bytes).

I’m guessing pickled eggs are zero-width spaces?

Most certainly! And the Right-to-Left embedding character must be pickled rinds: it ruins everything that comes after it.

"Nobody will ever put pickle juice in cereal"

-a person before getting poisoned by pickle juice cereal

I was thinking similar. Just another example of just because you can doesn't mean you should.
