Languages
Everything kobana says to a person comes out in Portuguese, English or Spanish: help, progress messages, prompts, errors and the page the browser shows at the end of login. Endpoint descriptions (in --help and kobana schema) come translated from the specifications each product publishes.

What does not change
Command and flag names (including the Portuguese helpers, such as +emitir --valor), JSON keys and exit codes are the same in any language — so a script written in one language runs on any machine.
The CLI also sends Accept-Language, and APIs that translate their own messages respond in the same language.
