<p>Strict Permalinks does two things:</p>
<ol>
<li>Restricts the <code>post_name</code> portion of the permalink to alphanumerics and hyphens</li>
<li>Disables permalink editing once a post is published</li>
</ol>
<p>Like me, you may have been under the impression that post slugs are already restricted to alphanumerics and hyphens. In the current WordPress 2.8.5, a title that includes certain kinds of punctuation (e.g., “smartquotes”) will result in URL-encoded characters in the <code>post_name</code> field. Many browsers handle this oddity seamlessly, however this may cause difficulties when integrating with systems expecting a more limited URL syntax.</p>
<h3>Upgrade</h3>
<ol>
<li>Use the plugin updater in WordPress or…</li>
<li>Delete the previous <code>strict-permalinks</code> folder from the <code>/wp-content/plugins/</code> directory</li>
<li>Upload the new <code>strict-permalinks</code> folder to the <code>/wp-content/plugins/</code> directory</li>
</ol>
<h3>Usage</h3>
<ol>
<li>In all cases the <code>post_title</code> to <code>post_name</code> conversion (i.e., the <code>sanitize_title</code> filter) will be limited to a-z, 0-9 and hyphens (-).</li>
<li>If a post is not yet published, the permalink can be edited as usual.</li>
<li>Once a post is published, the permalink editing interface is disabled.</li>
</ol>


Strict Permalinks
