quotemeta is meant for regex metas which form a super-set of "string metas".
But what about the stringyfications from Data::Dumper (single quote) or Data::Dump (double quote)?
DB<62> use Data::Dumper qw/Dumper/
DB<63> $Data::Dumper::Terse = 1;
DB<64> $x= Dumper q(It's\x\\)
DB<65> print "<<<$x>>>"
<<<'It\'s\\x\\'
>>>
DB<66> chomp $x
DB<67> $x =~ s/^'(.*)'$/$1/
DB<68> print "<<<$x>>>"
<<<It\'s\\x\\>>>
DB<69>
edit
NB: If you wanna use $Data::Dumper::Terse think of localizing it or use the OO interface ...

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).
