FWIW Rust also has null-terminated strings available under its std::ffi module. I’m not sure it would be feasible to migrate C++ to the approach of multiple string types now, and I’m not sure it would have been the right approach for C++11 given C++’s approach to interop, but it’s definitely possible to support interoperability with those legacy APIs without constraining a default string type to null-termination.
