“ñáéíóúà èìòù”.upcase  
=\> “ñáéíóúà èìòù”

Shouldn’t String#upcase also upcase letters others than those from ‘a’  
to  
‘z’?:

“ñáéíóúà èìòù”.upcase  
=\> “ÑÁÉÍÓÚÀÈÌÒÙ”

To upcase beyond ASCII, try the Unicode gem:

% gem install unicode

Unfortunatelly this gem doesn’t install on Ruby 1.9.  
It uses:  
struct RString-\>ptr  
which is not valid in Ruby1.9.
