unsigned char *buffer = (unsigned char*)malloc(8);
buffer[0] =  [d1 bytes]  ;
buffer[1] =  [d2 bytes] ;
buffer[2] =  [d3 bytes] ;
buffer[3] =  [d4 bytes] ;

Not sure what you expect this to do. bytes return an array, and you are assigning the addresses of the arrays to char elements of your buffer. This buffer won't be filled with any of the data you expect, and the "data" from d2 will partially overwrite those from d1 etc.

Also, you shouldn't make much assumptions about the lengths of your byte arrays, especially not if using UTF-16.

In a word: You don't throw the data you expect at your conversion routine. Maybe check that in the debugger.
