The C term printer, used by erlang:display/1 and crash reports, and io_lib:format/2 with ~p both printed the empty binary as <<"">>, because an empty byte sequence counted as a printable string. OTP only uses the quoted form for non-empty printable binaries, and prints <<>>. Fixes: atomvm#2449 Signed-off-by: Peter Madsen-Mygdal <petermm@gmail.com>
