Subject: sorting Array of accentuated Strings


I've done a "self <=> anotherString" comparaison which works by itself :

class String
  def <=>( aString )
    [blahblahblah]
  end
end

however if i want to sort an Array of Strings, the Array is sorted as
usual within Ruby (put accentuated characters at the end) :

a = [ "�tre", "Fen�tre", "Etre" ]

b = a.sort { | i, j | i <=> j }
puts "b = [ " + b.join(", ") + " ]\n"
# => b = [ Etre, �tre, Fen�tre ]

c = a.sort  #<=>( aString ) NOT CALLED...
puts "c = [ " + c.join(", ") + " ]\n"
# => c = [ Etre, Fen�tre, �tre ]

Why, in the case of "c = a.sort", #<=>( aString ) isn't called ?
the comparaison within an Array could compare different kind of objects
like :

a = [ 0, "a", 9, Time.new ] ???
