Google Cloud Translate php API returning unicode characters instead of the characters themselves

I'm using Cloud Translate PHP sdk to translate strings from a JSON file, the problem is it returns the translated strings with unicode characters instead of the real characters, so I have to search and replace each one which is quite a hassle...

Example:

"Exp\u00e9riences"

Is there a way to return the characters instead of the weird unicode thingy?

My method:

public function translateJsonFile(Request $request)
    {
        $htmlString = '';
        $source = 'en';
        $target = 'it';

        $key = 'My key';

        $translate = new TranslateClient([
            'key' => $key
        ]);

        //$trans = new GoogleTranslate();

        $newArray = [];
        $json = File::get(base_path() . '/resources/lang/english.json');
        $array = json_decode($json, true);

        foreach ($array as $key => $value) 
        {
            //$result = $trans->translate($source, $target, $value);

            $text_translated = $translate->translate($value, [
                'source' => $source,
                'target' => $target
            ])['text'];

            $newArray[$key] = $text_translated;
            //sleep(1);
            usleep( 500000 );
        }

        $fileName = '/temp/translated-'.rand(1,1000).'.json';

        Storage::disk('public')->put($fileName, json_encode($newArray));

		return response()->json([
			'newArray' => $newArray,
        ]);
    }
