    Description

      QString fmt = "%1";
assert(fmt.arg(u8' ') == " "); // FAIL: result is "32" (on C++20, on C++17, it's correctly " ")

      The QLatin1StringView and QStringView overloads use the multi-arg code path for this, and accept u8' ' (as a character) only in C++17 builds (due to QTBUG-124365).
