RS.CLIPPY.INVISIBLE_CHARACTERS

Using an invisible character in a string literal, which is confusing

What it does

Checks for invisible Unicode characters in the code.

Why is this bad?

Having an invisible character in the code makes for all sorts of April fools, but otherwise is very much frowned upon.

Example

You don't see it, but there may be a zero-width space or soft hyphen some­where in this text.
