You are going to laugh, but we actually already have canonical tags implemented that use only bracketed URLs.
The original goal of canonicals was actually to deal with excess search parameters, not character-based URL inconsistencies (that issue reared its head unexpectedly during development).
But you are totally right, the canonical tags will still help consolidate everything. Thanks again. ;)
