Concept definition

        template<typename T>
        concept narrow_string_guard = !std::is_assignable_v<T &, std::string> &&
                                      !std::is_constructible_v<T, std::string>

Detailed Description

Excludes narrow-string conversions when classifying wide strings.

A type convertible from both std::string and std::wstring would match two categories. Outside MSVC the wide form wins, so the wide categories exclude anything narrow-convertible.
