Like this (untested):

   code_convert_string_norecord (SDATA (mystring), Qutf_16, 1);

Note the two differences:

  . To get a C string from a Lisp string, use SDATA (btw, why do you
    manipulate Lisp strings here?)

  . Converting a Lisp string into UTF-16 (or any other encoding) is an
    _encode_ operation, so the last argument to
    code_convert_string_norecord should be non-zero
