Regex umlaut inconsistencies between PHPUnit and just PHP, specific on Arch #4860

Closed FlyingHelix closed 2 years ago

FlyingHelix commented 2 years ago
Q A
PHPUnit version 9.5.11
PHP version 8.0.14
Installation Method Composer

Current behavior

When running a specific Regex it does not recognize ü, ä, ö, ß and similar, when not using the pattern modifier u at the end, although when running in normal PHP, without the extends TestCase, it recognizes fine. Only happens on Arch Linux so far. The files are UTF-8 encoded.

How to reproduce

When running Arch Linux, with kernel 5.15.13


use PHPUnit\Framework\TestCase;

class OutputTest extends TestCase{
  public function testOutput() {
    var_dump(preg_match('/^[\p{L}\p{Mn}\W]{8,128}$/', 'gülitgesWort'));
    var_dump(preg_match('/^[\p{L}\p{Mn}\W]{8,128}$/u', 'gülitgesWort'));
  }
}

$a = new OutputTest();
$a->testOutput();
?>

produces int(0) int(1)

but 

class OutputTest{
  public function testOutput() {
    var_dump(preg_match('/^[\p{L}\p{Mn}\W]{8,128}$/', 'gülitgesWort'));
    var_dump(preg_match('/^[\p{L}\p{Mn}\W]{8,128}$/u', 'gülitgesWort'));
  }
}

$a = new OutputTest();
$a->testOutput();
?>

produces int(1) int(1)

while on Windows 21H2, PopOS 21.10 and the php:alpine docker image both produce the same int(1), int(1). I am not sure, if this is specific to my installation, but i am setting up another Arch bases system to test on at the moment. I also asked in the Arch forum, if other arch users experience it as well, it may as well be an Arch issue, and not phpunits. composer info is

Sorry, but I stopped reading after "Only happens on Arch Linux so far" and "I am not sure, if this is specific to my installation".
