There are lots of other languages that support full UTF-8 in identifiers (e.g, Go) and the non-English-speaking world doesn't take advantage.

Every such such language does it insecurely. The only exceptions are Java, rust and cperl.

I rather have no unicode identifiers than insecure identifiers, which don't follow the unicode security guidelines for identifiers.

I've done a similar thing when I was writing a language (with generics) that compiled to Go and needed to implement name mangling. But in any case, this isn't an example of a non-native speaker using utf-8 to write in his native language. :)
