    copied!<p>There are heaps of Qs about this on this forum and on the web in general. But I don't just get it.</p> <p>Here is my code:</p> <pre><code>function updateGuideKeywords($dal) { $pattern = "/[^a-zA-Z-êàé]/"; $keywords = preg_replace($pattern, '', $_POST['keywords']); echo json_encode($keywords); } </code></pre> <p>Now, the input is <code>Prêt-à-porter</code>, and the output is <code>"Pr\u00eat-\u00e0-porter"</code>.</p> <p>Why do I get the '\u00e' ?</p> <p>And how can I alter my pattern to include the characters <code>ê</code>, <code>à</code> and <code>é</code> ?</p> <p><strong>EDIT</strong><br> humm... since it looks like a unicode / character issue, I might go for the solution I found on <a href="http://www.codeguru.com/forum/archive/index.php/t-318709.html" rel="nofollow noreferrer">this page</a>.</p> <p>Here they suggest doing something like this:</p> <pre><code>$chain="prêt-à-porter"; $pattern = array("'é'", "'è'", "'ë'", "'ê'", "'É'", "'È'", "'Ë'", "'Ê'", "'á'", "'à'", "'ä'", "'â'", "'å'", "'Á'", "'À'", "'Ä'", "'Â'", "'Å'", "'ó'", "'ò'", "'ö'", "'ô'", "'Ó'", "'Ò'", "'Ö'", "'Ô'", "'í'", "'ì'", "'ï'", "'î'", "'Í'", "'Ì'", "'Ï'", "'Î'", "'ú'", "'ù'", "'ü'", "'û'", "'Ú'", "'Ù'", "'Ü'", "'Û'", "'ý'", "'ÿ'", "'Ý'", "'ø'", "'Ø'", "'œ'", "'Œ'", "'Æ'", "'ç'", "'Ç'"); $replace = array('e', 'e', 'e', 'e', 'E', 'E', 'E', 'E', 'a', 'a', 'a', 'a', 'a', 'A', 'A', 'A', 'A', 'A', 'o', 'o', 'o', 'o', 'O', 'O', 'O', 'O', 'i', 'i', 'i', 'I', 'I', 'I', 'I', 'I', 'u', 'u', 'u', 'u', 'U', 'U', 'U', 'U', 'y', 'y', 'Y', 'o', 'O', 'a', 'A', 'A', 'c', 'C'); $chain = preg_replace($pattern, $replace, $chain); </code></pre> <p><strong>EDIT 2</strong><br> This is my solution so far:</p> <pre><code>function updateGuideKeywords() { //First we replace characters with accents $pattern = array("'é'", "'è'", "'ë'", "'ê'", "'É'", "'È'", "'Ë'", "'Ê'", "'á'", "'à'", "'ä'", "'â'", "'å'", "'Á'", "'À'", "'Ä'", "'Â'", "'Å'", "'ó'", "'ò'", "'ö'", "'ô'", "'Ó'", "'Ò'", "'Ö'", "'Ô'", "'í'", "'ì'", "'ï'", "'î'", "'Í'", "'Ì'", "'Ï'", "'Î'", "'ú'", "'ù'", "'ü'", "'û'", "'Ú'", "'Ù'", "'Ü'", "'Û'", "'ý'", "'ÿ'", "'Ý'", "'ø'", "'Ø'", "'œ'", "'Œ'", "'Æ'", "'ç'", "'Ç'"); $replace = array('e', 'e', 'e', 'e', 'E', 'E', 'E', 'E', 'a', 'a', 'a', 'a', 'a', 'A', 'A', 'A', 'A', 'A', 'o', 'o', 'o', 'o', 'O', 'O', 'O', 'O', 'i', 'i', 'i', 'I', 'I', 'I', 'I', 'I', 'u', 'u', 'u', 'u', 'U', 'U', 'U', 'U', 'y', 'y', 'Y', 'o', 'O', 'a', 'A', 'A', 'c', 'C'); $shguideID = $_POST['shguideID']; $keywords = preg_replace($pattern, $replace, $_POST['keywords']); //Then we remove unwanted characters by only allowing a-z, A-Z, comma, 'minus' and white space $keywords = preg_replace("/[^a-zA-Z-,\s]/", "", $keywords); echo json_encode($keywords); } </code></pre>
