In this case, the selectedtext is a property that contains no positional information. You can't do math on selectedtext unless it just so happens to contain a number. So, to do what you want you would need to use selectedchunk instead, check it to see a) if its only an insertion point (word 4 of the selectedchunk - word 2 of the selectedchunk will = -1 if this is the case) then if I recall correctly, word 2 of the selectedchunk is the cursor position so checking char (word 2 of the selectedchunk - 1) will give you the char reference that you're looking for.
Again, i'm not a unicode guy so someone correct me if you have to do things different.
