You can internationalize your maps in several different mapping frameworks.
Google Maps API
Using the right language settings with the Google Maps API allows your users to see map labels and directions in their own language.
MapBox Studio / TileMill
If your users might not have the right fonts to see your map labels, you can use a tile service like MapBox Studio / TileMill to generate image tiles.
First, install the right language font on your computer.
MapBoxGL
Labels in MapBoxGL are rendered as text by the browser. The user may need a web font installed to show your labels.
