It's work but it's not such a mountain that pokemon as a franchise as to cut corners here.
Pokémon games these days have a team working for translation in French anyway.
There's still a limit as far as space goes but it can't absolutely be that low that it can't be worked around.
and gender neutral doesn't really work in French, it's male by default but that's the language.
That's what I meant, I don't think character limits are a problem anymore. The only problem now is making it sound natural, which is sometimes impossible.
French being incompatible with a neutral gender is a pretty big problem if you're trying to leave the gender choice out of the game entirely.
