Layers with umlauts in name not showing on map

[fdetsch]

Special case for certain, but layers are not showing on the interactive map if the layer.name includes German umlauts (and possibly other special characters). The initial zoom, legend, and displayed layer name are correct. Output of sessionInfo() attached below.

library(mapview)

mapview(
  breweries
  , layer.name = "Bräustätten" # works for "Braeustaetten"
)

Works on my machine. Can you please try to install both mapview and leafem from github and see whether that helps?

Nope, this has no effect – at least not with the default branches.

Can you open the map in your browser and see if there are any errors in the browser console?
