The following is inefficient, but should give you an idea of a general
approach
you could use to carry out this transformation.  It only deals with
numeric
code character entities, as in your example text.

echo "&#73;&#74;aaaa&#75;" | gawk '
{
    while (match($0,/&#[0-9]+;/))
	$0 = substr($0, 1, RSTART-1) sprintf("%c", substr($0, RSTART+2)+0) \
		substr($0, RSTART+RLENGTH)
    print
}'
