The difference with $Data::Dumper::Useperl = 1; is related to strings that can be represented entirely without utf8. On ingest eval makes the usual perl heuristic about utf8, and gets it wrong:
#!/usr/bin/perl -w
use utf8; # so source code is utf-8 encoded
use Data::Dumper;
$data1 = 'ä ☺'; # a-umlaut, space, smiley
$data2 = 'ä '; # a-umlaut, space, space
$Data::Dumper::Useperl = 1;
$dump1 = Dumper( $data1 );
print $dump1;
$dump2 = Dumper( $data2 );
print $dump2;
print "\n";
$Data::Dumper::Useperl = 0;
$dump1 = Dumper( $data1 );
print $dump1;
$dump2 = Dumper( $data2 );
print $dump2;
print "\n";
Output
$VAR1 = "\x{e4} \x{263a}";
$VAR1 = 'ä ';
$VAR1 = "\x{e4} \x{263a}";
$VAR1 = "\x{e4} ";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
