How can i unescape "slash" additionally to basic function {% autoescape false %}? - symfony

Question

I'm working on an app with Symfony/Twig, and I want to scan a directory and add all photos of this directory in a Bootstrap carousel.
Controller
public function index(int $id, ManagerRegistry $doctrine): Response
{
$entityManager = $doctrine->getManager();
$establishment = $entityManager->getRepository(Establishment::class)->find($id);
$establishmentName = $establishment->getEstablishmentName();
$establishmentDirectory = $this->getParameter('media_directory').'/establishments_pages/'.$establishmentName;
$establishmentAssetDir = '/ressources/uploads/establishments_pages/'.$establishmentName;
$photos = [];
$buttons = [];
$count = 0;
$count1 = 1;
if ($establishmentDirectory) {
$results = scandir($establishmentDirectory);
foreach ($results as $value) {
if ($value !== '.'
&& $value !== '..'
&& $value !== 'Suite Deluxe'
&& $value !== 'Suite standard'
&& $value !== 'Suite VIP') {
if ($count === 0) {
$button = '<button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" class="active" aria-current="true" aria-label="Slide '.$count1.'"></button>';
$photo = '<div class="carousel-item active"><img src="{{ asset("'.$establishmentAssetDir.'/'.$value.'")}}" class="d-block w-100" alt="Photo de l\'hotel"></div>';
array_push($buttons, $button);
array_push($photos, $photo);
$count++;
$count1++;
} else {
$button = '<button type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide-to="'.$count.'" aria-label=" Slide '.$count1.'"></button>';
$photo = '<div class="carousel-item"><img src="{{ asset("'.$establishmentAssetDir.'/'.$value.'")}}" class="d-block w-100" alt="Photo de l\'hotel"></div>';
array_push($buttons, $button);
array_push($photos, $photo);
$count++;
$count1++;
}
}
}
} else {
echo 'Le dossier n\'existe pas.';
}
dump($photos);
return $this->render('establishment/establishment.html.twig', [
'id' => $id,
'establishment' => $establishment,
'establishmentName' => $establishmentName,
'establishmentDirectory' => $establishmentDirectory,
'buttons' => $buttons,
'photos' => $photos,
]);
}
When I dump $photos in this Controller, I obtain what I'm looking to do: real paths to the photos with all slashes.
array:3 [▼
0 => "<img src="{{ asset("/ressources/uploads/establishments_pages/Chez Eros/HM_francesca-saraco-dS27XGgRyQ-unsplash-625fd4f334cbd.j ▶"
1 => "<img src="{{ asset("/ressources/uploads/establishments_pages/Chez Eros/eddi-aguirre-ZAVHbpOn4Jk-unsplash-625fd4f33559c.jpg")}}" class ▶"
2 => "<img src="{{ asset("/ressources/uploads/establishments_pages/Chez Eros/marten-bjork-n-IKQDCyrG0-unsplash-625fd4f3364ae.jpg")}}" class ▶"
]
But when Twig interprets this code, it transforms all slashes to spaces, EVEN IF I put the unescape function on false!
The TWIG code :
<div id="carouselExampleIndicators" class="carousel slide" data-bs-ride="carousel">
{% autoescape false %}
<div class="carousel-indicators">
{% for button in buttons %}
{{ button }}
{% endfor %}
</div>
<div class="carousel-inner">
{% for photo in photos %}
{{photo}}
{% endfor %}
</div>
{% endautoescape %}
<button class="carousel-control-prev" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="visually-hidden">Previous</span>
</button>
<button class="carousel-control-next" type="button" data-bs-target="#carouselExampleIndicators" data-bs-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="visually-hidden">Next</span>
</button>
</div>
The result in debug toolbar on chrome:
<img src="{{ asset(" ressources="" uploads="" establishments_pages="" chez="" eros="" hm_francesca-saraco-ds27xggryq-unsplash-625fd4f334cbd.jpg")}}"="" class="d-block w-100" alt="Photo de l'hotel">
I already try to add "|raw" inline on the photo variable in TWIG, but it doesn't change anything!
Can anybody help me to keep my paths?
