### Description

The following code:

https://3v4l.org/kihD6

```php
<?php

var_dump(preg_match('/.*/', hex2bin('ff')));
var_dump(preg_match('/^$/', hex2bin('ff')));
var_dump(preg_match('/.*/u', hex2bin('ff')));
var_dump(preg_grep('/.*/u', [hex2bin('ff')]));
```

Resulted in this output:
```
int(1)
int(0)
bool(false)
array(0) {
}
```

But I expected this output instead:
```
int(1)
int(0)
bool(false)
bool(false)
```


### PHP Version
