\Q and \E don't work inside interpolations. They only work in regexp literals (m/here/, s/here// and qr/here/). Solutions:
# Text.
$text = 'Renata';
$window =~ /\b\Q$text\E\b/ism
and
# Uncompiled regexp.
$text = 'Renata';
$regexp = '\\b' . quotemeta($text) . '\\b';
$window =~ /$regexp/ism
and
# Compiled regexp.
$regexp = qr/\b\QRenata\E\b/ism;
$window =~ $regexp
Note:
The s modifier is useless if you don't use ".".
The m modifier is useless if you don't use "^" or "$".

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).
