Not sure about Turkish, but I know for a fact that when you have a team of Chinese devs work on a Chinese software project Mandarin starts to show up in the codebase. And while usually it's written in pinyin (the standard Chinese romanization system) since most programming languages assume ASCII, it's obvious that those people could benefit from being able to use Chinese characters in place of ASCII and English. If your argument is "sure, then let them invent/fork $LANGUAGE to suit their needs", just take note that if you're a language designer/developer that wants to see the language widely adopted, it's detrimental to have the attitude that ASCII is enough for everybody. There's no reason to have (for example) "Arabic-python" just because somebody insists on ASCII instead of UTF-8 even though there's little technical reason not to support it.
