Accessing strings

If I something like word = "ruby"
can't I do something like (I thought it was possible)

word[0] -> r
word[1] -> u
word[2] -> b
word[3] -> y

Trying something like that now and it's giving me "weird" numbers

Yet I'm trying it (both program and irb) and it gives me weird numbers

irb(main):010:0> word = "ruby"
=> "ruby"
irb(main):011:0> puts word[0]
114
=> nil
irb(main):012:0> puts word[2]
98
=> nil
irb(main):013:0> puts word[3]
121
=> nil

So what am I doing wrong ?
TIA

We _just_ discussed this:

Also check the documentation.

Or even on your own machine:

$ ri String#
... ri output
