Check for "almost quote"

[Felienne]

Since #1085 we give better error messages for backticks (#721):

But, now we do not give a more specialised warning, something like: You enclosed the string in ` instead of '.

Rust has a notion of "similar characters" with lovely error messages (see: https://github.com/rust-lang/rust/issues/25957) like this:

note: Unicode character U+37E (Greek Question Mark) looks like a semicolon, but is not.

Would be really cool if we implemented something like that too!

Maybe confusables can help here? I don't know whether it can do the same thing that the Rust PR can, but maybe it's a start.

Ah good to get a reminder of old issues! What do you think @jpelay, one for you too (but not with all too high priority I think?)
