This is NOT the place to use a regex. Just use the substr() function to
remove all characters after the 4096th.
substr($entry, 4096) = "" if length($entry) > 4096;
or
$entry = substr($entry, 0, 4096);

Perl's strings can't be manipulated as arrays at the high-end level
(that's not to say they're not implemented as char* in the source code).
