/*
* NOTE:
* YYC MARK:
* According to the documentation introduced in CppReference.
* The standard library is guaranteed to provide several specific specializations of \c std::codecvt.
* The UTF8 char type in UTF8 related specializations of \c std::codecvt is different.
* It is also independend from we defined char type.
* So it is essential define a type which can correctly trigger specific specializations of \c std::codecv in there.
* The UTF8 char type in UTF8 related specializations of \c std::codecvt is different in different C++ standard.
* But the oldest C++ version YYCC supported is C++ 23, char8_t is the only viable UTF8 char type for \c std::codecvt.
* So we can simply and safely use it to correctly trigger specific specializations of \c std::codecv in there.
