also shows Welsh names in Welsh-speaking parts of Wales (using a .poly
from Jerry, actually), but that's really a solution to a different
problem (described at
http://www.openstreetmap.org/user/SomeoneElse/diary/42069 ).

I heartily agree that both english & welsh names need to be shown side
by side, for this reason can I suggest that when editing names to add
a Welsh name if the existing name is English (London Road for
instance) also add a name:en tag. If we can work just with name:cy &
name:en tags in rendering we can achieve a lot more.
"Displaying side by side" (perhaps one bracketed after the other) is
very doable in lua;

is an example of that in another context.
The basic overlay idea works for street & place names (and one can
offset welsh language names in one direction and english names in the
opposite ones. Finding colours which dont create conflicts and
legibility issues is another thing. I'll see if I can fish out an
example from my carto rendering experiments.
I suspect that an overlay may not be the way to go (if possible) because
you won't get collision avoidance between the overlay and the main
map*. Here's an example of that:
https://map.atownsend.org.uk/maps/map/map.html#zoom=16&lat=53.2387&lon=-1.01152
those two names apply to the same bit of track but Mapnik's clever
enough to ensure there's no clash.
Best Regards,
Andy
* although maybe having the overlay also containing every other piece of
text, but in "transparent on a transparent background", may work!
