It will be..
Khaled hasn't explicitly shared his plans for utf-8 support but I'd bet that he plans on making everything work as it should. Full support for unicode, however, does not happen overnight. In fact, Khaled started unicode support 2 years ago and there is still plenty left to do.
You can expect this issue to be addressed.. when, however, I don't know.
Unicode covers a lot more than just UTF-8! There's UTF-8 BOM, UTF-16, etc.
Unicode support is bad under windows...
