of "~ts" to allow an integer between the t and s for forcing a <br>
particular unicode interpretation. That would allow a list of bytes to <br>
be interpreted as UTF8, to provide the same output as a binary:<br>
1> io:format("~ts~n",[<<16#C2,16#A2>>]).<br>
¢<br>
ok<br>
2> io:format("~t8s~n",[[16#C2,16#A2]]).<br>
¢<br>
ok<br>
<br>
I was also wondering if bytestring types would be added to Erlang/OTP, like:<br>
-type nonempty_bytestring() :: nonempty_list(byte()).<br>
-type bytestring() :: list(byte()).<br>
<br>
They are useful in iolists to ensure only bytes (not other integers) are <br>
in nested lists.<br>
