Re: [jruby-user] Iterating over characters in a String ?

Ok, I'll take a look at that.

So, in the meantime, for iterating over characters, is there a better
solution than this ?

def each_char(str)
 0...str.length do |i| puts str[i] end
end

This is quite important. I'm writing my app in Brazilian Portuguese,
which with all its accents ("Olá, como vai você ?") does not fit in
the ASCII subset of UTF-8, and I really need Unicode.
