Performance and simplicity. MSEgui does not need the overhead of 
multi-encoding/multi-charsize. At the moment msestring=UnicodeString for FPC 
2.4 which is perfect. I fear FPC will drop this simple solution where it was 
ahead of Delphi.

No problem with me. What will be the new name? Although I find it strange that 
WideString is reference counted on Linux and the same WideString type is not 
reference counted on Windows and for porting COM code one could define 
WideString = OLEString or OLEString = WideString to be Delphi compatible.
