lupdate does not work with wchar_t with QT_TR_NOOP

If text is wide character then lupdate does not picks it up. I agree that Qt's translation mechanism in general expect const char* i.e. UTF-8 encoded strings
But then what is confusing here is that it works with Qt6.5.x

Attached is the small example  This has text string

QT_TR_NOOP(L"Welcome to our application!")

When lupdate of Qt6.2 is used to create .ts file this does not find this but if lupdate of 6.5 is used it finds it.

Attached is tiny example. 

using Qt6.2 lupdate run lupdate . -ts translations_en.ts

and then using 6.5 run same.
