Description
Example from Qt itself:
1: QDEBUG : tst_QLocale::formatDate() expected data of type 'QString', got 'char8_t [64]' for element 1 of data with tag 'unicode in format string' 1: QFATAL : tst_QLocale::formatDate() ASSERT: "false" in file /home/marc/Qt/qtbase/src/testlib/qtestdata.cpp, line 105 1: FAIL! : tst_QLocale::formatDate() Received a fatal error.
It's pretty obvious what's happening: instead of the QVariant(const char*) ctor, it's now using QVariant::fromValue(), which stores it as a char8_t[64], and it doesn't know that the two are convertible.

As a user of Qt, whose code works in C++17, I want my code to work in C++20, too.
