Strings
 
- Parse lines in a String object with #each_line or #lines, instead of #each
- String#ord returns the UTF-8 index
- "x".ord is the new way of doing ?x
- ?a == "a" (and no more "97")
- "A".ord == 65, "ABC".ord == 65

Ruby 1.9 Notes by Peter Cooper (http://rubyinside.com/19.txt)
 
INTRO
- Welcome to the Ruby 1.9 Walkthrough
- A walkthrough or a review, if you will, of how Ruby 1.9.2/3 compares to Ruby 1.8.7
- I've gone through and tried 100s of things on Ruby 1.8.6, 1.8.7, and 1.9.2 to see what has changed
- Matz quote
- Many of the videos and blog posts about 'what's new in Ruby 1.9' are out of date because some decisions were reversed
or because they were written when 1.8.6 was out, but then stuff got backported to 1.8.7
enumerators, for example!
