The problem here is just that arithmetic converts everything back 
to integers and writefln is a bit picky about types. You can 
print it though by casting it back to dchar:

         writefln("%c", cast(dchar)('\U0001F0A1'+1));

My fonts don't support these chars but it should print out if you 
do that.
