Uh, no? You are not supposed to be able to read this valid Unicode string literal in Korean: `"그뤼고 이 문좌열은 일부려 기ㅖ버역을 어럽게하러고 오타비문이 산개해 있구먼요."`
Also a significant portion (and possibly the majority) of codes would be ever read and written by a small group of people, often sharing a common language other than English, so non-English code is just fine for them. If you are saying that a public library should be written in English, I almost agree---there would be some exceptions though.
