seems like we're missing the case of zero-width space

\ "\u200B": '',

should do the trick

Hey,
I didn't have any success typing that one into vim. I get this: <200b> and it behaves as a single wide character.
Btw, other troll characters all display properly.

If this is not something related to my setup, I'd just leave this as-is. With <200b> it's obvious something is wrong.. Can't call that "trolling", really.

What are you getting when you try to type that into vim?
