Dear Peter,
there have been lengthy discussions about Unicode and Ruby on this list.
I remember responding to an upcase/downcase question here:
_http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/183176_
(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/183176)
You can do character encoding conversions using iconv, which is
part of Ruby. There is documentation and examples available
here:
_http://www.ruby-doc.org/stdlib/libdoc/iconv/rdoc/index.html_

Best regards,
Axel
