I got error in Chrome in my XML file: https://media.mostrami.pl/feed/zanox.xml?asdfsadfa after upgrade from PHP 5 to 7.
error on line 148745 at column 26: Input is not proper UTF-8, indicate encoding !
Bytes: 0xC4 0x87 0x20 0x6A
I validated the file using xmllint and did not get any error. I'm pretty sure that the content is in UTF-8 (worked fine in PHP5, validated by xmllint, checked by file -I xml_filename)
What's wrong?
