[Interest] QStringLiteral and UTF-16 string literal "u"

[Cathal Tummon (ctummon)]

Hi there,

I'm trying to figure out if the "u" is still necessary at any point when using QStringLiteral.
It seems to be always prepended according to the source code:

https://codebrowser.dev/qt5/qtbase/src/corelib/text/qstringliteral.h.html
https://codebrowser.dev/qt6/qtbase/src/corelib/text/qstringliteral.h.html

But the documentation still references it in examples and even has a caveat that it could be necessary for some compilers:
https://doc.qt.io/qt-6/qstring.html#QStringLiteral

Just wondering if this is still the case and I am missing something?

Regards,
Cathal
