#41000 [Opn->Csd]: Document DOM/libxml's handling of character encodings (UTF-8)

ID: 41000 Updated by: vrana@php.net Reported By: phpbug at elitecoders dot com -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Irrelevant PHP Version: Irrelevant New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "DOM extension uses UTF-8 encoding. Use utf8_encode() and utf8_decode() to work with texts in ISO-8859-1 encoding or Iconv for other encodings." Previous Comments: ------------------------------------------------------------------------ [2007-04-08 19:13:42] ezyang@php.net While I think that the DOM documentation needs to be improved overall, this bug is covering a very specific issue, namely dealing with UTF-8 in libxml. I have changed the summary accordingly. ------------------------------------------------------------------------ [2007-04-05 01:39:29] phpbug at elitecoders dot com Description: ------------ I've been using PHP's DOM (both dom and domxml) for over a year and it's only today after a lot of research I've realized that because PHP uses libxml, and libxml uses UTF-8 internally that I have some serious issues with character encoding because of being ignorant of this. I'm strongly suggesting a large note near the beginning of the DOM pages where knowing this information would be useful. In addition to the note, it might also be a good idea to link users to http:// xmlsoft.org/encoding.html where it goes over the whole utf8 thing and why they use it and blah blah blah. Definitely a very visible note should be added here: http://www.php.net/manual/en/ref.dom.php On http://www.php.net/manual/en/function.dom-domdocument-construct.php "The encoding of the document as part of the XML declaration." Here, it should be clarified that if you pass a character encoding, it does not affect the internal character encoding and you still need to utf8_encode characters outside of the normal ASCII range. On http://www.php.net/manual/en/function.dom-domelement-construct.php and http://www.php.net/manual/en/function.dom-domtext-construct.php it needs to at least warn that characters outside of normal ascii need to be utf8 encoded. I'm sure there are other pages as well, I need to get going though.
