I'm not sure if this works quite as intended, but I was at least 
able to produce a UTF-16 decode error rather than a UTF-8 decode 
error by setting the file orientation before reading it.

     import std.stdio;
     import core.stdc.wchar_ : fwide;
     void main(){
         auto file = File("UTF-16LE encoded file.txt");
         fwide(file.getFP(), 1);
         foreach(line; file.byLine){
             writeln(file.readln);
         }
     }
