As I understand it std::string, std::wstring, std::u16string and std::u32string are mainly intended to store utf-strings.
Since at least utf-8 and utf-16 have variable storage sizes for their code points the question for the "size of a string" storing either encoding is ambiguous:

  • On one hand there is the storage size of the string, which can be obtained by either std::basic_string::size() or std::basic_string::length().
    [Why two methods to get the same result?]
  • On the other hand the amount of stored code points.
    Sadly without a standard way to ask for, or have I missed something?
