This is a curiosity more than anything: Does there exist a programming language that allows variables, functions, and classes to be named using using Unicode rather than ASCII (except, of course, for special characters such as '+')? Do any popular languages have support for this?
Also, related to this, if any common language supports Unicode, then is there any way to convert an existing API into a language of the user's own choice? It seems like it would be helpful to give a programmer the ability to learn an API in their own language. I imagine downloading a standard API (for instance boost) and then downloading the standard translation mapping and then being able to program in my native language.
