What would perhaps be a worthwhile feature is the ability to input already known unicode names into a text box after seeing the results, to feed the database with more useful matches.
For example, tried drawing a somewhat joined 'TM' a couple times but no matches for 'Trademark symbol', however a way to manually input that unicode/name might provide the database with a positive match for the next user trying to find it.
