    <p>OK thank you for showing your complete code. The problem is that you are passing the contents of <code>$body</code> as a URL parameter, and so the HTTP protocl needs various characters escaping to pass them through properly.</p> <p>You can achieve this with the <a href="https://metacpan.org/module/URI%3a%3aEscape" rel="nofollow"><code>URI::Escape</code></a> module, and you will no longer have to do the sanitizing that you do on line 125 and the lines following <code># clean the body</code>.</p> <p>This program uses a string containing all the problem characters you have identified, and translates it using the module. If you use <code>uri_escape</code> on the contents of <code>$body</code> before appending it to the URL for Curl then everything should work.</p> <pre><code>use strict; use warnings; use URI::Escape 'uri_escape'; my $body = '%localappdata% â &amp; '; print uri_escape $body; </code></pre> <p><strong>output</strong></p> <pre><code>%25localappdata%25%20%E2%20%26%20 </code></pre> <hr> <p><strong>Update</strong></p> <p>For manipulating URLs in general it is best to use the <a href="https://metacpan.org/module/URI" rel="nofollow"><code>URI</code> module</a> which will do all necessary escaping for you in both the path and the query part of the URL.</p> <p>The program below shows how to generate the URL you need to pass to <code>$curl-&gt;setopt</code> using this method</p> <pre><code>use strict; use warnings; use URI; my $url = URI-&gt;new('https://this/is/the/url'); my $body = '%localappdata% â &amp; '; $url-&gt;query_form(body =&gt; $body); print $url, "\n"; </code></pre> <p><strong>output</strong></p> <pre><code>https://this/is/the/url?body=%25localappdata%25+%E2+%26+ </code></pre> <p>(Note that this method uses <code>+</code> instead of <code>%20</code> for space characters. Either is acceptable in the query portion of a URL.)</p> <p>This URL can be set as a Curl option directly by writing</p> <pre><code>$curl-&gt;setopt(CURLOPT_URL, $url); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
