How problematic would this be really?
The captionless layer could simply orient against the default text, and the
localised renderings just did the best they could against that.
If text wasn't placed perfectly, well it's less than ideal, but at least we'd
have localised tiles! Could this work?
I'm simply trying to find a way to localise tiles on osm.org, in a resourceful
way! Seems like many people are positive on this.
Are there any other ideas for how to set up a localised tile infrastructure?
