Your mention of non-english posters translating, as long as they are only translating from their language to english, the far better translator is: deepl

I do not know why they only translate to English, but maybe they felt that by concentrating on getting the full meaning of the translation, plus the idioms, is more important. I've tried it and it does give a better translation -though, I would not depend on it doing a fantastic job on poetry....that needs something more intuitive than anything we can do which does not include a human mind.
