In Ruby 1.8, String#[] with a single Integer argument returns the  
character, which as you've found is the ASCII code for the character.

In Ruby 1.9, String#[] returns a 1-character string (and you can apply  
String#ord to it if you want the value)

So filename[2..2] will give you a 1-character string in both versions.  
I'd stick with it.
