Those tell the compiler that your source has been stored in that  
particular code page, and then the compiler will convert all string  
constants *from* the specified code page *to* widestring (which then  
at run time is converted back to the active ANSI code page; not to  
UTF-8).

If you want to do that, you have to wrap all your string constants  
with utf8encode(). That takes a widestring as parameter and returns an  
UTF-8 string. However, that is not Delphi-compatible either.

In the long term, native utf8string support will solve your problem,  
but right now what you want is not possible afaik.
