This is a test site for an OpenStreetMap map that allows you to change the language of the labels. [More Infos...]
Choose language with selector or type a language code (something like "de" or "ru") or a language combination (something like "de,fr,en") into input box. Use the special string "_" for the "name" tag without language. You can also add a second language in parentheses by writing something like "fr|de" or "fr|_".
You can use any language code available in OSM. Languages are tried in order with fallback to the plain "name" tag.
