I don't know, for me as a non-native speaker the words in a programming language are just memorised tokens, they could just as well be symbols or emojis. The bigger deal is libraries and documentation. For instance Microsoft is attempting to localise all their SDK documentation, and at least for German it's a nightmare, either the translations are done by non-technical people, or algorithms, sometimes the information is twisted in a way that reads like correct German, but doesn't contain any useful information, or is even plain wrong.
