Yeah! I`m learning to program in ruby but i can`t understand what i`m  
getting char erros!

My code:

#!/usr/bin/ruby

class Teste  
def initialize(nome, sobrenome, idade)  
@nome = nome  
@sobrenome = sobrenome  
@idade = idade  
end  
end

class Impressora \< Teste  
def printer  
puts @nome  
puts @sobrenome  
puts @idade  
end  
end

@pessoa = Impressora.new(“a”, “b”, 10)  
@pessoa.printer

The ouput:

m0bile \> ./teste.rb  
./teste.rb:14: Invalid char `\302' in expression ./teste.rb:14: Invalid char `\240’ in expression

I`m on Mac Leopard

Use an editor/viewer that will show characters outside of the normal  
ASCII range and then remove them.  
Or, delete and retype the line.

Ruby _code_ (excluding Strings, etc with unicode) must be proper ASCII.
