<p>This is a souped-up version of the <a href="https://wordpress.org/plugins/normalizer/" title="Normalizer - WordPress Plugins" rel="ugc">Normalizer plugin</a> by <a href="https://profiles.wordpress.org/zodiac1978/" rel="nofollow ugc">Torsten Landsiedel</a>.</p>
<p>It adds WP filters to normalize UTF-8 data coming into the system to the <a href="https://www.w3.org/International/docs/charmod-norm/#choice-of-normalization-form" title="Choice of Normalization Form" rel="nofollow ugc">de facto web standard Normalization Form C</a>.  The Unicode Consortium report is at <a href="http://www.unicode.org/reports/tr15/" rel="nofollow ugc">Unicode Normalization Forms</a>.</p>
<h4>Polyfills</h4>
<p>For best performance <a href="http://php.net/manual/en/intl.installation.php" rel="nofollow ugc">install</a> (if possible) the <a href="http://php.net/manual/en/intro.intl.php" rel="nofollow ugc">PHP Internationalization extension <code>Intl</code></a>, which includes the PHP class <code>Normalizer</code>.</p>
<p>However the plugin works without the PHP <code>Intl</code> extension being installed, as it uses (a modified version of) the <a href="https://github.com/symfony/polyfill/tree/master/src/Intl/Normalizer" rel="nofollow ugc">Symfony <code>Normalizer</code> polyfill</a>.</p>
<p>Also text pasted into (most) inputs is normalized immediately using the JavaScript <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/String/normalize" rel="nofollow ugc"><code>normalize()</code> method</a>.  For browsers without normalization support, the <a href="https://github.com/walling/unorm" rel="nofollow ugc">unorm polyfill</a> is used.</p>
<h4>Background</h4>
<p>For further info, see the WP Trac ticket <a href="https://core.trac.wordpress.org/ticket/30130" rel="nofollow ugc">#30130 Normalize characters with combining marks to precomposed characters</a> and this <a href="https://make.wordpress.org/core/2016/05/17/may-17-feature-projects-chat-and-prompt/#comment-30300" rel="nofollow ugc">Make WP Core comment</a>.</p>
<p>The plugin also works around the Safari-specific issues raised by the WP Trac ticket <a href="https://core.trac.wordpress.org/ticket/22363" rel="nofollow ugc">#22363 Accents in attachment filenames should be sanitized</a>.</p>
<h4>Scanner</h4>
<p>For existing data, the plugin includes an administration tool to scan and normalize the database.  <strong>Important:</strong> before using this tool to normalize, please <a href="https://codex.wordpress.org/WordPress_Backups" rel="nofollow ugc">backup your database</a>.  This is especially important if your database contains non-normalized serialized data, as this plugin uses the same suck-and-see technique as interconnect/it’s <a href="https://interconnectit.com/products/search-and-replace-for-wordpress-databases/" rel="nofollow ugc">Database Search and Replace Script in PHP</a> to deal with serialized data, and is fallible.</p>
<h4>And</h4>
<p>A google-cheating schoolboy French translation is supplied.</p>
<p>The plugin should run on PHP 5.2.17 to 7.1, and on WP 3.9.13 to 4.7.1.</p>
<p>The project is on <a href="https://github.com/gitlost/unfc-normalize" rel="nofollow ugc">github</a>.</p>
