Getting certain characters from a string

ruby-talk
1

I have a string that I need to get certain characters at a given index.
However, doing something like str[0] gives the ascii number, not the actual
character. How do I get it to give me the character?

I believe you're looking for the chr method

As in

string[0].chr

str[0,1]

This is compatible with both ruby 1.8 and ruby 1.9.
