Can one person compete in a contest in multiple languages?

In single player challenges, I can complete them in multiple languages. For optimization challenges, people can compete with a submission for each language that are ranked separately.

Is it possible to do the same in a contest? Can I submit a solution in an obscure language (for the contest language achievements) while also submitting a more competitive solution in Java or C++ or something? Will these both be ranked, or only the last on that was submitted?

I would propose (if it isn’t this way already) that people should be able to compete and be ranked in multiple languages. Each submission should count for language achievements, but only their best submission will actually be ranked and count for CodingPoints and affect the standings of other players.
