QAnyStringView is designed to replace overload sets containing QString and QChar, among others, so it needs to accept types that merely implicitly convert to QString and QChar. It achieves this by maintaining a hidden container to hold the converted QString or QChar for the duration of the full-expression, much like the compiler would do if the function took QString/QChar. This patch adds a check for the single-char ctors to determine whether they convert or not, by comparing QASV::data() to the address of the QASV's argument. While it would be interesting to have the same test for QString, that is outside the scope of this patch.
