Slovak and Czech too (definitely even more languages). Both languages have all nouns, adjectives, numerals AND verbs gendered. You could theoretically refer to a non-binary person as a you (in plural form) - that is however used mainly for speaking/referring to someone more respectable. Then you have the they form, which is not recommended to be used in singular due to it being used during feudalism to refer to the aristocracy), and then it (which is terrible too, as it seems like you are speaking to an item, not a human being). If you want to invent a different pronoun, good luck with making it not sound weird, as we use 7 grammatical cases and declension; in general, the grammar is incredibly complex.
