Bug #4549: Can't start class names with non us-ascii chars

irb(main):003:0> #encoding: UTF-8
irb(main):004:0* class Åäö; end
SyntaxError: (irb):4: class/module name must be CONSTANT
class Åäö; end
             ^
        from /usr/local/bin/irb:12:in `<main>'

• Status changed from Open to Rejected

It is because Å is not a uppercase letter.

I beg the differ! ÅÄÖ are all uppercase letters, as oppose to åäö, in the Swedish alphabet.

The problem this is occurring for us is that we can't the name the objects in your domain model correctly. We don't wan't to translate it to English because we want to communicate with our customers using their terms and not constantly have to translate back and forth..

Use decomposed string. In this case,

class A\u030Aa\u0308o\u0308
end

Ruby considers it is begin with ASCII uppercased character: constant.
