Pages where title-with-en-dashes and title-with-ASCII-hypen aren't the same

Fork of Outdated AnomieBOT EnDashRedirectCreator redirects by Anomie

This query is marked as a draft This query has been published by Anomie.

Chances are that something like "0-1" and "0–1" should have one redirect to the other or should both redirect to the same place. This lists titles where that is not the case.

It excludes namespaces where weird mismatches are probably ok (e.g. userspace, draftspace) or where redirects don't work as expected (e.g. modulespace)
