Bug #74909 [NEW]: XMLReader reports "Input is not proper UTF-8" on long Chinese strings

From: lilydjwg at gmail dot com Operating system: Arch Linux x86_64 PHP version: 7.1.7 Package: XML Reader Bug Type: Bug Bug description:XMLReader reports "Input is not proper UTF-8" on long Chinese strings Description: ------------ The error position is at the last character (\xef\xbc\x8c in UTF-8). If I make the string longer, the position doesn't change. If I make it one character shorter than the example, the error disappears. I've read bug #72181 but can't reproduce that one. My libxml2 version is 2.9.4+96+gfb56f80e-1 The XML doc for testing: <?xml version="1.0" encoding="UTF-8"?> <properties> 制馬吃富不國助病以孩上容留消生強德，準大指總產如戰上是個！沒目人起如物對了話外多年至性己外頭出假。在館演量難調代什如常千苦友議，學字而的響過紙看正家！玩車一，是華是體過記用說感公媽間城石也都於教行，獲驚稱重眼發工，層上由的間近要過將去資球我老來許推、種得海在中個產程的治教他院一；持一建情。你室隊花……放成動， </properties> Test script: --------------- <?php $reader = new XMLReader(); $reader->open("a.xml"); while($reader->read()) { } Actual result: -------------- PHP Warning: XMLReader::read(): /home/lilydjwg/tmp/a.xml:3: parser error : Input is not proper UTF-8, indicate encoding !
