Could... roll your own? Although if you wanted it to be UTF-8 
output instead would require a second pass or better yet changing 
how the i iterated.

char[] getLine16LE(File inp = stdin) {
     static char[1024*4] buffer;  //4k reusable buffer, NOT thread 
safe
     int i;
     while(inp.rawRead(buffer[i .. i+2]) != null) {
         if (buffer[i] == '\n')
             break;

         i+=2;
     }

     return buffer[0 .. i];
}
