[Bug]: The `toHaveSuspiciousCharacters` method identifies Cyrillic characters as suspicious

What Happened

In our project we use annotations to generate the OpenApi file and specify the description using Cyrillic.

When calling the architectural test arch()->preset()->php() it returns an error:

Expecting 'app\Enums\AlertTypeEnum.php' to not include suspicious characters.
at app\Enums\AlertTypeEnum.php:11
at vendor\pestphp\pest-plugin-arch\src\Expectations\Targeted.php:46
at vendor\pestphp\pest-plugin-arch\src\Blueprint.php:137
at vendor\pestphp\pest-plugin-arch\src\Expectations\Targeted.php:43
at vendor\pestphp\pest-plugin-arch\src\SingleArchExpectation.php:162
at vendor\pestphp\pest-plugin-arch\src\SingleArchExpectation.php:146

Enum class:

<?php

declare(strict_types=1);

namespace App\Enums;

use OpenApi\Attributes as OA;

#[OA\Schema(
    schema: AlertTypeEnum::class,
    description: 'Тип алерта', // this line
    type: 'string',
    enum: AlertTypeEnum::class,
)]
enum AlertTypeEnum: string
{
    case Ok      = 'OK';
    case Warning = 'WARNING';
    case Error   = 'ERROR';
}

How to Reproduce

Create any file and add annotation with Cyrillic. For example:

<?php

declare(strict_types=1);

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Symfony\Component\Console\Attribute\AsCommand;

#[AsCommand('test', 'Привет')]
class TestCommand extends Command
{
    public function handle(): void {}
}

And now just run the check:

arch()->preset()->php();

Result:

Expecting 'app\Console\Commands\TestCommand.php' to not include suspicious characters.

Notes

No response

Start by locating the toHaveSuspiciousCharacters implementation behind arch()->preset()->php(), using the stack entries in vendor/pestphp/pest-plugin-arch/src/Expectations/Targeted.php and Blueprint.php as entry points. Reproduce the check with the Cyrillic annotation shown in the issue, then verify that Cyrillic descriptions are accepted while genuinely suspicious characters are still rejected.
