- [ ] **not** a usage question (ask them on https://stackoverflow.com/questions/tagged/phpspreadsheet or https://gitter.im/PHPOffice/PhpSpreadsheet)

What is the expected behavior?

error message :
htmlspecialchars(): charset `0' not supported, assuming utf-8

in file :
..../vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Shared/XMLWriter.php:90

Trace :
#0 [internal function]: rbinit_exception_error_handler(2, 'htmlspecialchar...', '/usr/share/ranc...', 90, Array)
#1 vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Shared/XMLWriter.php(89): htmlspecialchars('2009-04-02T16:2...')

#3 vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Writer/Xlsx.php(260): PhpOffice\PhpSpreadsheet\Writer\Xlsx\DocProps->writeDocPropsCore(Object(PhpOffice\PhpSpreadsheet\Spreadsheet))

Solution

Can you try to change the line

return $this->writeRaw(htmlspecialchars($text));

to

return $this->writeRaw(htmlspecialchars($text, ENT_QUOTES, 'UTF-8'));

on line 90 of file phpspreadsheet/src/PhpSpreadsheet/Shared/XMLWriter.php

Thanks
