What's the Point of the prefix ? operator in Ruby 1.9

Question

I\'m just wondering what applications it has. I believe in 1.9 the prefix ? would return the string version of that character.

?a   #=> \"a\"
?\\t  #=>         


        

Answer 1

in ruby 1.8 and earlier

?a 

would return the ASCII version of 'a' char.

in 1.9 it just returns the string ( just as you've assumed )
