'ASCII value of character in Ruby
How do I obtain the ASCII value of a character in Ruby 1.9?
I searched the Internet far and wide, but without success. I tried ?x and "x"[0], but all they return is "x".

You can also use
ruby-2.0.0p353 > "x".sum
=> 120
ruby-2.0.0p353 > "a string".sum
=> 792
The 'sum' method will find the sum of all character codes, but if you put only one character it will give you the code of that one only.

I was also stuck with this, ord only works from string to number and not vice versa. The solution is:
def getChar(a):
return a.chr
end
