Sorry, +1 from me generally, but one question about QLatin1String vs QStringLiteral.  My research suggests some of these should be QStringLiteral, but please let me know if I'm mistaken.


src/core/kdesktopfile.cpp (line 307)
<https://git.reviewboard.kde.org/r/125106/#comment59445>

    Since this gets converted to a QString immediately, should this not be a QStringLiteral?  There doesn't seem to be an override for the + operator for QLatin1String, so it has to convert to UTF-16 anways.  There are a bunch of such cases below as well.
    
    I double checked against QStringBuilder, and I don't see it helping either.  It still does the conversion anyways.
