It’s perfectly possible.

irb(main):001:0> Документ = Class.new
=> #<Class:0x00000001b5e0e0>
irb(main):002:0> obj = Документ.new
=> #<#<Class:0x00000001b5e0e0>:0x00000001b57e48>

You may want to overwrite the class’ ::inspect method to display
properly in IRB. But note that it is regarded as a local variable
rather than a constant; you could use a namespace module with module
methods (which can be called using the :: syntax) to achieve what you
want, i.e. something like

=========================
module Namespace

  X = Class.new
  def X.inspect; "Документ"; end
  def X.name; "Документ"; end

  def self.Документ
    X
  end

end

obj = Namespace::Документ.new
=========================

Note that I assign the new class to a separate constant (X) instead of
just returning Class.new in the Namespace::Документ() method, because
this would return a new class each time you call it (making checks
with #kind_of? useless).
However, using local names doesn’t seem a good idea to me altogether,
most programming languages are inspired by English and mixing it with
another language makes it look weird. Even worse, a framework like
Rails expects English nouns to be used as classnames, because it
automatically derives a whole bunch of further names from it by
inflecting the word according to English grammar rules. Local names
break such frameworks completely.

This obviously requires Ruby 1.9.
