Without DisableUTF8RTL you can pass an UTF8String to a non "var" String
parameter. The compiler will add some checks, but they don't change the
encoding. Same for return values String to UTF8String.

With DisableUTF8RTL passing UTF8String to String changes encoding. So
every function needs an overloaded wrapper function. No need to copy
the implementation.
