What would you use for a regular string where you just had, essentially
a vector of char, wchar_t, char8_t, char16_t, char32_t, or unsigned
char, but didn't care about encoding? I want to differentiate between
this case and the case where I know that there's a particular encoding.
A lot of times you just know you got a string from one system call and
you're passing it to another and you don't care about encoding. If you
used a validating utf8 std::string, if it turned out not to be utf-8
you'd throw or return an error for nothing. It's not a good fit for
existing things, it would just be something going forward for things
that knew that they were using utf-8.
