Very nice and useful thing. Actually I needed a tool like that, so thanks for sharing it 

I tested it in Photoshop CS2 and I managed to run the scripts, although it requires two small changes in order to make it work:
1. For some weird reason this is syntax error according to CS2:
// @TODORemoving "@" in all the lines that start with // @TODO fixes it.
2. This is even more weird, in FoFntMaker.jsx file, the line 352:
if(f !== null)is always false in CS2, resulting in alert("Error opening FOFNT file, nothing saved") even if you choose save.
I suppose there is something wrong with !== operator in CS2 JavaScript engine.
I fixed it by reversing the condition:
    if(f === null)
    {
        alert("Error opening FOFNT file, nothing saved");
    }
    else
    {
        if(f.open('w', 'TEXT', '???'))
        {
            f.write(o);
            f.close(); 
        }
        else
            alert("Could not open file for writing");
    }alternative solution is to simply change "!==" to "!=".
