Changing this table requires a working copy format bump...
I'm more surprised on how the url can enter the low level libraries without being canonicalized?
Especially since we re-canonicalize paths from 'entries' on upgrading to wc_db.db based formats. (Over the years we found a few extreme rare corner cases, but '+' in a path doesn't look uncommon to me)
