Accessing Garamond PP kerning table/values?

Hi there

I recently purchased Adobe's Garamond Premier Pro typeface. In order to do some translation work i need to create some extra characters (the license allows this), they will be letters with dots underneath them. After which i will use a script to deal with the kerning of these newly created letters.

My question is, can i/how can i access the kerning tables of this typeface? If i can just add the values to the script that would make life a whole lot easier than having to do this manually.

Any info or advice is most welcome.

Thank you!
