No, it was just an idea to ease interop between C and other languages
and avoid the frequent errors people will hit when trying to exchange
strings.

The other solution is documentation, i.e. very clearly explaining
somewhere that C has a different string format from other languages
and that strings sent from language A to C won't be usable as such
(without specifying the length in every single function call, or
copying).
