Your input looks like a perfect candidate for "paragraph mode" using the switches -n and -00 (see perlrun): 

#!/usr/bin/perl -n00

/^TEXT;\nLAYER 13[1-7];\nTEXTTYPE 0;.+STRING (.+?);/s and print $1,"\n
+";

The //s modifier is necessary, since without it, the "." character would not match a newline.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
