ksh93 supports character constants in integer expressions, thus
	$(('`'))
will expand to the character value for grave and $(('u')) will
give the character value for small u.  However, character values
can be signed so that
	$(('ù'))
expands to a signed number.  However, you can do
	printf "%u\n" $(('ù' &0xff ))
to get the unsigned value.
