Unless a backup copy of result_normal_plus[2] is made first, 
result_normal_plus[2]='\0'; is likely to clobber the 
binary data payload. 

It'd be better to deal with the two ASCII character as 
just two ASCII characters (that are not in a string), 

   printf("header = '%c%c'\n", result_normal_plus[0],result_normal_plus[1])

or to _copy_ them into a nul-terminated string. 

   header[0]=result_normal_plus[0];
   header[1]=result_normal_plus[1];
   header[2]='\0';
   printf("header = '%s'\n", header);
