I mean the same is true pretty much for most languages once English (or sometimes other) loanwords come into the picture. German for example doesn't technically have a "j" sound like in "John", but it's nowadays used all the time in English loanwords (some speakers might substitute "ch", which does exist in native German words, but most especially younger people don't). The letter "j" is otherwise pronounced like English "y".
