Some functions use null-terminated C strings, but all have an equivalent
that allows you to embedd '\0'. I would suggest that you take a look
through this ongoing thread in this NG:
  how to construct a string with embedded NULLs

A vector can be initialized using a memory range:

  std::vector v( myString, myString + myStringLength );
