How can I get Ruby to treat the index of a string as a character (rather than the ASCII code)?

I am checking to see if the last character in a directory path is a '/'. How do you get ruby to treat the specific index of a string as a character rather than the associated ASCII code?

For example the following always returns false:

dir[dir.length - 1] == '/'

This is because dir[dir.length - 1] returns the ASCII code 47 (rather than '/').

Any thoughts on how to interpret 47 as '/'? Or is there a completely different way to handle this in the first place?

thanks.
