Edit report at https://bugs.php.net/bug.php?id=47875&edit=1 ID: 47875 Comment by: markokarjalainen at kolumbus dot fi Reported by: thomas dot koch at ymc dot ch Summary: No option to set HTML input encoding Status: Verified Type: Feature/Change Request Package: DOM XML related Operating System: Debian Lenny PHP Version: 5.2.9 Block user comment: N Private report: N New Comment: Any plan to fix this real old bug? 1. loadHTML should be always UTF-8 as default, like DOMDocument self is. 2. If user give charset in DOMDocument::__construct(), then loadHTML should to be use it. 3. If imported HTML contains charset, then use it. Maybe this kind of change not broke the world? Previous Comments: ------------------------------------------------------------------------ [2020-10-23 15:22:50] cmb@php.net Not a solution, but likely a viable workaround would be prepending the HTML string with a BOM ("\xef\xbb\xbf" for UTF-8), see <https://3v4l.org/ArhNb>. ------------------------------------------------------------------------ [2018-07-22 18:36:11] anrdaemon at freemail dot ru Prefixing does not work. The default input encoding of DOMDocument is IS-8859-1 contrary to the documentation that says the input should be UTF-8 encoded. If you prefix your document with "<?xml …", it will change mode to UTF-8 regardless of encoding specified in the XML declaration, and mangle the declaration itself. https://3v4l.org/HL5It In short, DOMDocument is largely unusable for HTML, only well-formed XML with explicit declaration gives you a small hope of success. ------------------------------------------------------------------------ [2015-12-22 21:19:12] nathan dot renniewaldock at gmail dot com This really does need to be supported. Though libxml2 is partly to blame for ignoring <meta charset="utf-8"> For now, workaround is to prefix the HTML with either <?xml version="1.0" encoding="UTF-8"?> or <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> ------------------------------------------------------------------------ [2015-07-10 15:55:59] cmb@php.net Related To: Bug #49705 ------------------------------------------------------------------------ [2013-01-07 17:34:42] crmalibu at gmail dot com I also stumbled upon libxml2's htmlSetMetaEncoding() here: http://www.xmlsoft.org/encoding.html#implemente and http://www.xmlsoft.org/html/libxml-HTMLtree.html This would be a very welcome feature addition. Currently, hacky php code like this festers in the wild due to the lack of being able to specify the encoding: $encodingHint = '<meta http-equiv="Content-Type" content="text/html; charset=utf-8">'; $dom->loadHTML($encodingHint . $html); // lol make it utf8 or maybe some str_replace() or use of html tidy if the developer was feeling robust that day... This really sucks, because to me it looks like the functionality is totally there in libxml2. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
