Sorry to drag this out, but even if my compiler is broken.
By the looks of it I do not need to manually add the "u" , it seems to be added by the QStringLiteral() macro itself?

Correct. The u is not required for any compliant compiler. The problem is only if your compiler is broken (i.e., MSVC).

See the discussion on commit d80b0eb12c477592b590b768e21dc26c137beadc[1] and on the MSFT bug report.
