* lib/rexml/xmltokens.rb: Add missing non ASCII valid characters

to element name characters. Now, REXML name tokens exactly
  match "[5] Name" in the XML spec and "[4] NCName" in the
  Namespaces in XML spec. See comment about the details.
  [Bug #9539]  [ruby-core:60901]
  Reported by Mario Barcala. Thanks!!!

* test/rexml/xpath/test_node.rb: Add tests for the above case.
