Correct. QLocale sets itself up, which is not a problem.

QTranslator takes filenames as parameters. That requires the locale 8-bit codec 
to be working. That *only* works after QCoreApplication has been instantiated.

So I'm against using QTranslator before QCoreApplication. We should not 
recommend any mainstream API to be used before QCoreApplication. The creation 
of the application object should generally be the first thing in the main 
function.
