How to translate the language switcher links In Drupal 8.1 the language switcher (block can be placed in a region) shows the languages labels in English:
English | German | French

I want to translate it. Visiting mysite/de the label should be in German:
Englisch | Deutsch | Französisch

mysite/fr --> labels should be translated in French

The words "German" and "French" and "English" are translated into all languages in my drupal installation. Yet the language switcher shows the labels in English all the way.

How translate it?
I'm still looking for this same answer, but there is a way to translate them, so you can have them as English | Deutsch | Français in the language switcher for all languages: just translate the language name on /admin/config/regional/language
