May be I'm wrong in my understanding of binary string literal is wrong.
But using non-ASCII letters in binaries has been the place where I
first realized, that I did store my erlang source code in utf-8 instead
of latin-1.

The following code does print "Size: 6" if encoded in latin-1 and "Size:
12" if encoded in utf-8.



    B = <<"üüüüüü">>,
    io:format("Size: ~w~n", [byte_size(B)]).

best regards,
