Google announced Friday that their App Indexing protocol, the ability to markup your content and have Google deep link to your Android apps content from the search results, now supports other languages. It started off slowly and then rolled out internationally but for English language Android apps only.
Now, it supports Chinese (Traditional), French, German, Italian, Japanese, Brazilian Portuguese, Russian, and Spanish.
With the announcement, the first set of internationalized apps include Fairfax Domain, MercadoLibre, Letras.Mus.br, Vagalume, Idealo, L'Equipe, Player.fm, Upcoming, Au Feminin, Marmiton, and chip.de.

Bing also has quietly added app linking for Windows based apps in the Bing search results.
