Webflow POST API issue

Hi, I am using webflow api to post data in collection. But all data is not sending to webflow. When I fix this issue then description not sending in correct format. There are norwegian language words in description and these are not going in correct format and it changes it to wrong format…

curl_setopt_array($curl, array(
CURLOPT_URL => ‘https://api.webflow.com/collections/63592ce1583ed824ac8bf805/items?live=true’,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => ‘’,
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => ‘POST’,
CURLOPT_POSTFIELDS =>‘{
“fields”: {
“name”: "’.$title.‘",
“stillingsbeskrivelse”: "’.$data_desc.‘",
“stillingsingress”: "’.$jobtitle.‘",
“arbeidsgiver”: "’.$emp_name.‘",
“bedriftsinformasjon”: "’.$data_emp_desc.‘",
“firma-nettside”: "’.$emp_homepage.‘",
“ansettelsesform”: "’.$engagementtype.‘",
“soknadslink-eller-e-post”: "’.$applicationurl.‘",
“soknadsfrist”: "’.$applicationdue.‘",
“arbeidsplass”: "’.$address.‘",
“city”: "’.$city.‘",
“positioncount”: "’.$positioncount.‘",
“extent”: "’.$extent.'",
“_archived”: “false”,
“_draft”: false

	  }
	}',

	  CURLOPT_HTTPHEADER => array(
		'Accept-Version: 1.0.0',
		'content-type: application/json',
		'Authorization: Bearer 5901bbea02f9f2d0b6e70b18416e755bafd60e3434534b40f7319eb9c37',
		'Cookie: wf_exp_uniqueId=dded4948-71e1-4994-8a33-7297f2b890f7; wf_logout=1665660419415'
	  ),
	));
		$response1 = curl_exec($curl);
		$val1 = json_decode($response1); 

Error::
