Take a look at the documentation for Integer#chr:

http://rdoc.info/stdlib/core/1.8.7/Integer:chr

If you have a number between 0 and 255, that method should return you
the ascii character.  If you're confused about why you got that number
in the first place, take a look at the String#[] documentation:

http://rdoc.info/stdlib/core/1.8.7/String:%5B%5D

That method is heavily overloaded, so read the documentation carefully.
 Under Ruby 1.8, you'll get a number back if you give a single numerical
argument.  You'll get a single character string under Ruby 1.9.

Also, make sure that you always read the documentation appropriate for
the version of Ruby that you're using.  It's much more of an issue with
regard to string handling differences between 1.8 and 1.9 than other areas.
