Or even better, use FPC 2.6 AnsiString and UnicodeString and drop the 
encoding aware FPC 2.7 AnsiString. ;-)

BTW, please have a look into the different string concatenation 
compilerproc, it is probably not so easy to model that with equal or 
better performance with TBytes and operator overloading. Is it possible 
with operator overloading to combine different types?
"
<TBytes>:= <TBytes> + 'stringconstant' + <TBytes> + <AnsiString>;
"
