I refuse to care about this. A single dash is all I will ever use. I see no possible reason to use the other two.

Throwing my hat in here. The sub millimeter difference in the length of a dash conveys no additional meaning or clarity. It is impossible to argue me out of this position.

It's not like you can reliably write these consistently by hand either without going over the top in length to make it extremely obvious.

Here's some examples where the en dash could make things more clear:

-5--2°C

post-war-pre-digital era

See sections 10-O-15-Q

-5°C to -2°C

post-war - pre-digital era (not a sentence any sane person would use anyway).

See sections 10-O - 15-Q

Try our New York-London flight connection! (no kind of dash clears this one up without fixing capitalisation).

The last one was a gotcha: it's their newly established York–London flight!

Try Our New York–London Flight Connection.

Or if it was New York:

Try Our New York – London Flight Connection.

Note the additional spaces. Agree on the capitalization though.

> Try Our New York – London Flight Connection.

I'd wager serious money that if you put that on a sign and surveyed people, at least in the US, they'd all still conclude it is a "New York" to "London" flight.

What's the use of a communication tool, if it doesn't actually communicate anything to real people?

York doesn't have an active airport
