You can now display maps in languages of your choice on testwiki. I made two pages to demonstrate the new features, on testwiki [1] and testwiki2 [2] (embedded maps on test2 are dynamic; those on test are static until you click to pop up an enlargement).
By default, internationalized maps display in the language of the wiki (which is English for the testwikis). So to experiment with these features, you’ll want to use the two new mapframe parameters we’ve added. Just insert them into your map frame tags.
lang=”xx” Shows map labels in the language you specify with the short language codes used for each wiki.
lang=“local” Shows map labels in the languages of the territory mapped (essentially opting out of internationalization).
Right now, internationalization works only with mapframe, not maplink (which should be working some time next week). You can read more about this new feature and how to use it on the Map Improvements 2018 project page, under Updates [3]. Our plan is to wait a week or two and assess user comments about the feature. At that point, we’ll decide whether to move forward with a general release or keep making fixes.
So please try the new features out and leave feedback on the Map Improvements 2018 talk page
