Schema validation does not work with %xx sequences in path to phpunit.xsd

[veugenio]

Q	A
PHPUnit version	9.5.0
PHP version	7.4.13
Installation Method	Composer

Summary

PHPUnit returns "Warning - The configuration file did not pass validation!" when running inside a directory containing a %xx sequence as name.

Apparently this is related to this bug https://bugs.php.net/bug.php?id=55374 and if you change this code, it works as expected:
vendor/phpunit/phpunit/src/Util/Xml/Validator.php:26

// $document->schemaValidate($xsdFilename);
$document->schemaValidateSource(file_get_contents($xsdFilename));

Current behavior

When running vendor/bin/phpunit we have this:

PHP Warning:  DOMDocument::schemaValidate(): Invalid Schema in /var/www/a%25/vendor/phpunit/phpunit/src/Util/Xml/Validator.php on line 26

  Warning - The configuration file did not pass validation!
  The following problems have been detected:

  Line 0:
  - failed to load external entity "/var/www/a%25/vendor/phpunit/phpunit/phpunit.xsd"
  - Failed to locate the main schema resource at '/var/www/a%25/vendor/phpunit/phpunit/phpunit.xsd'.

  Test results may not be as expected.

How to reproduce

• Create a directory called a%25 (or another name with the same pattern);
• Init a new composer project inside this directory that requires PHPUnit;
• Create a basic phpunit.xml;
• Run vendor/bin/phpunit;

Expected behavior

Run without warnings:

PHPUnit 9.5.0 by Sebastian Bergmann and contributors.
