There's no easy way to tell how much storage the strings occupy. There 
are functions like GetHeapStatus and GetFPCHeapStatus, but they return 
the total amount of memory occupied by everything that the application 
allocates - objects, dyn.arrays, strings etc.
However, you may hack into RTL at the NewAnsiString / NewWideString / 
NewUnicodeString procedures and install hooks that will record the 
number of bytes requested. That shouldn't be too difficult to do.
