Because ~w prints the term representation as it is.
If you use ~p, it's almost the same, but pretty-printed,
so a string (a list of printable character codes) will be
printed within double quotes.

To print just the characters in a string (or atom),
without any surrounding quotes, use ~s, as in:

   io:format("jbss msg  ~s~n", [Mymsg])
