[bitcoin-dev] BIP 39: Add language identifier strings for wordlists

Mon Jan 8 15:23:53 UTC 2018

> Let me re-phrase: Is it a known thing for users to actually use it?

yes. Based on language stats from the app stores, roughly 30% to 40% of
Copay users have their backup on a language
other than English, and we constantly get requests to support new languages
in BIP39.
