Correct way is to register the collation you need. AFAIK it's also 
possible to register that at runtime, but I have to admit that I haven't 
followed the discussion of the features of fpwidestring that closely, so 
someone else will need to definitely answer that...

The main difference is that cwstring uses the Widestring manager of the 
system's C library while fpwidestring is a full Pascal Widestring manager.
