Well, hevc already is a standard. It’s too late now. AV1 will need some time until it’s widely adopted.

I‘ve only ever read the German versions but to my knowledge, they have been originally written in french and it’s up to the translators to also translate the humour. As is generally with any media (books, movies, games, etc.).
That can work very well and sometimes translations can even add additional humour that the originals didn’t have.
