@tsusanka: We would like to translate both T1 and TT firmwares to help onboard non-English users. We will first tackle this in Core, if porting goes well, we will achieve this in T1 using the Core codebase.

What is most likely obvious but seems better to write it explicitly is that a incorrect translation could lead to a security issue where the user is confirming a different action than intended. We need to be careful.

original issue: #987
