And of course code which assumes that the string can only ever contain hex digits is an exploit waiting to happen. Code which doesn't assume the type of content of a variable but contains a string constant is only exploitable by editing the source file and munging the constant. See my answer to davido below.
perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
