This would solve the specific language problem, but let's say a person from China would want to use their characters. I'm still not sure why $content = mb_convert_encoding($content, 'UTF-8'); works for ü (umlauts and other special characters but not for lets say Chinese ones.

I tired your first option and saving all the files in UTF-8. This didn't solve the problem. Then I tried the forcing BOM: function writeUTF8File($fname,$content) { $file=fopen("files/$fname.txt", "w"); fwrite($file, pack("CCC",0xef,0xbb,0xbf)); fwrite($file,$content); fclose($file); } writeUTF8File($fname,$content); Didn't solve the case either. Maybe I'm not using it right. A weird case when using utf-8 and playing with $content = mb_convert_encoding($content, 'UTF-8'); It works for German letters like üöë... etc, but not for chinese letters or Slovenian letters like š č ž. This code also works for German: (it would work with chinese or š č ž letters). $ent =array('À'=>'À', 'à'=>'à', 'Á'=>'Á', 'á'=>'á', 'Â'=>'Â', 'â'=>'â', 'Ã'=>'Ã', 'ã'=>'ã', 'Ä'=>'Ä', 'ä'=>'ä', 'Å'=>'Å', 'å'=>'å', 'Æ'=>'Æ', 'æ'=>'æ', 'Ç'=>'Ç', 'ç'=>'ç', 'Ð'=>'Ð', 'ð'=>'ð', 'È'=>'È', 'è'=>'è', 'É'=>'É', 'é'=>'é', 'Ê'=>'Ê', 'ê'=>'ê', 'Ë'=>'Ë', 'ë'=>'ë', 'Ì'=>'Ì', 'ì'=>'ì', 'Í'=>'Í', 'í'=>'í', 'Î'=>'Î', 'î'=>'î', 'Ï'=>'Ï', 'ï'=>'ï', 'Ñ'=>'Ñ', 'ñ'=>'ñ', 'Ò'=>'Ò', 'ò'=>'ò', 'Ó'=>'Ó', 'ó'=>'ó', 'Ô'=>'Ô', 'ô'=>'ô', 'Õ'=>'Õ', 'õ'=>'õ', 'Ö'=>'Ö', 'ö'=>'ö', 'Ø'=>'Ø', 'ø'=>'ø', 'Œ'=>'Œ', 'œ'=>'œ', 'ß'=>'ß', 'Þ'=>'Þ', 'þ'=>'þ', 'Ù'=>'Ù', 'ù'=>'ù', 'Ú'=>'Ú', 'ú'=>'ú', 'Û'=>'Û', 'û'=>'û', 'Ü'=>'Ü', 'ü'=>'ü', 'Ý'=>'Ý', 'ý'=>'ý', 'Ÿ'=>'Ÿ', 'ÿ'=>'ÿ','&' =>'&'); $content=strtr($content, $ent); Is there any other universal code that will do the same as the code above, only for all languages?

No problem thanks for having a go. The files create a problem no matter what encoding type they're saved with. Using fopen or fwrite doesn't help either. I don't think it's a matter or OS or browser, because special characters only work on some servers, so maybe getting the server information and comparing it with another one would be good. For example the installation of this works on a localhost without a problem. (with same OS and browser). Any other suggestions?

1 day bump.

Using <meta http-equiv="content-type" content="text/html; charset=utf-8" /> on all pages, check the deafult.php to see the template if interested. Another day, another bump.

Bumping this.

Someone recently reported that a simple 10kb CMS I made doesn't work with special characters on some servers. I'm not sure why this happens and I'm looking for some help. The CMS files are attached and I'm also pasting them over here, since there are only 2 main files. On some servers, when entering a special character, it returns false. And on some it saves the character, but once it reads it again, it becomes a questionmark. You can have a test on how it doesn't work over here. (password for login is admin)(click anywhere on the content to edit it). Special characters to test: š č ž. (or any other special characters like the german umlauts: ü ö) This is the index.php <?php function getSlug( $page ) { $page = strip_tags( $page ); preg_match_all( "/([a-z0-9A-Z-_]+)/", $page, $matches ); $matches = array_map( "ucfirst", $matches[0] ); $slug = implode( "-", $matches ); return $slug; } $page = $_REQUEST['page']; if(!$page) $page = "Home"; $contentfile = $page = getSlug( $page ); $content[0] = @file_get_contents("files/$contentfile.txt"); if(!$content[0]) $content[0] = "Your page named <b>$page</b> is created.<br /><br />\n\nClick here to start editing your newly created page!"; $title = @file_get_contents('files/title.txt'); if(!$title) $title = "Your title here"; $slogan = @file_get_contents('files/slogan.txt'); if(!$slogan) $slogan = "- Your slogan over here!"; $menu = @file_get_contents('files/menu.txt'); if(!$menu) $menu = "Home"; $description = @file_get_contents('files/description.txt'); if(!$description) $description = "Enter your website description over here!"; $keywords = @file_get_contents('files/keywords.txt'); if(!$keywords) $keywords = "Enter, your, keywords, for, your, website, over, here"; $copyright = @file_get_contents('files/copyright.txt'); if(!$copyright) $copyright = "Your website (c) 2011"; $mess = 'Powered by <a href="http://krneky.com/en/wondercms">WonderCMS</a>'; //config section $hostname = $_SERVER['PHP_SELF']; $hostname = str_replace('index.php', '', $hostname); $hostname = str_replace($page, '', $hostname); $theme = $_REQUEST['theme']; if( !file_exists("$theme.php") ) $theme = "default"; $cookie = 'wondercms'; // cookie ame $expirytime = time()+86400; // expire time if(isset($_REQUEST['logout'])) { setcookie($cookie,'',time() - 84000); // remove cookie/ header('Location: ./'); exit; } $password = @file_get_contents("files/password"); if(!$password) { savePassword("admin"); } if($_COOKIE[$cookie]) { $lstatus = "<a href='$hostname?logout'>Logout</a>"; } else $lstatus = "<a href='$hostname?login'>Login</a>"; if(isset($_REQUEST['login'])) { getLoginForm(); } require("$theme.php"); // Functions function editTags() { global $cookie; if(!$_COOKIE[$cookie]) return; echo "<script type='text/javascript' src='./js/editInplace.js'></script>"; } function displayMainContent() { global $cookie, $content, $page; if($_COOKIE[$cookie]) { echo "<div class='title'><div id='change'><span id='$page' class='editText'>$content[0]</span></div></div>"; } else { echo $content[0]; } } // display section content function displaySectionContent($cnum) { global $cookie, $content; if($_COOKIE[$cookie]) { echo "<div id='change'><span id='$cnum' class='editText'>$content[$cnum]</span></div>"; } else echo $content[$cnum]; } function displayMenu($stags,$etags) { global $menu; $mlist = explode("<br />",$menu); $num = count($mlist); for($ix=0;$ix<$num;$ix++) { $page = trim($mlist[$ix]); if(!$page) continue; echo "$stags href='$page'>$page $etags \n"; } } function getLoginForm() { global $content, $msg; $msg = ""; if (isset($_POST['sub'])) loginSubmitted(); $content[0] = " <center> <form action='' method='POST'> <h2>Password</h2> <input type='password' name='password' /><br /> <input type='submit' name='login' value='Login'> <h2>$msg</h2><br /> <script src='js/editInplace.js'></script> <div class='all'> <a href='javascript:showhide()'>Click to change your password</a> <br /><br /> <div id=hide style='display: none;'> Type your <b>old</b> password above, and your new one in the field below. <h2>New Password</h2> <input type='password' name='new' /><br /> <input type='submit' name='login' value='Change'> <input type='hidden' name='sub' value='sub'> </div></div> </form></center>"; } function loginSubmitted() { global $cookie, $password, $msg, $expirytime, $submitted_pass; $submitted_pass = md5($_POST['password']); if ($submitted_pass<>$password) { $msg = "<b class='wrong'>Wrong Password</b>"; return; } if($_POST['new']) { savePassword($_POST['new']); $msg = "Password changed!<br /><br />Please login again."; return; } setcookie($cookie,$password,$expirytime); header('Location: ./'); exit; } function savePassword($password) { $password = md5($password); $file = @fopen("files/password", "w"); if(!$file) { echo "<h2 style='color:red'>*Error* - unable to access password</h2><h3>But don't panic!</h3>".
