When I call `nl_langinfo`, it returns "ASCII" by default. I can call `setlocale(LC_CTYPE, "C.UTF-8")` to make it return "UTF-8", but I was wondering if there was a way through environment variables to make C.UTF-8 be the default. 

I tried setting LC_CTYPE and LC_ALL to C.UTF-8, but this doesn't seem to get picked up by `nl_langinfo` (or by `setlocale(LC_CTYPE, NULL)`).

thanks!

PS: I'm trying this on Alpine.
