Keywords, names, filenames don't retain their meanings from English, so it's not important where they came from. And error messages use the same few English words, but mostly all those keywords, names, filenames. Documentation available in local languages is the only important part here. But documentation and other reading materials is an issue for people who are already many years in programming and the deeper they go into the field, the more necessary it becomes to learn English.
