Vladimir, unfortunately Unicode and internationalisation in general is
hard. In C code (that's what Ruby is written in), checking whether a
letter is an ASCII capital one is dead simple. Checking whether is it
an Unicode capital requires decoding it from whichever variant of UTF
is was encoded in and looking it up in one oh huge tables defining
various letter properties to check if it is a capital or not. You
would probably have to change parsing rules and a lot of internal code
to make it possible, since capital first letter is the only difference
between Ruby constant or variable.

I think you should try posting to Ruby's bug and feature tracker, at
http://bugs.ruby-lang.org/.
