Gform_after_submission blocking unicode characters

Get Help

Hello, I am using the gform_after_submission action to post submission data to an external database. When Japanese or other international users submit form fields the data shows with missing characters. Weirdly, I can see the characters fine in the “Entries” section of gravity forms. And the database accepts unicode characters. I believe these characters are being stripped when I use the rgar function to assign the values to the $data array: ‘first_name’ => rgar( $entry, ‘14’ ).

Here is the function:

function post_to_mydatabase( $entry, $form ) {

function post_to_url($url, $data) {
	$fields = '';
	foreach($data as $key => $value) {
		$fields .= $key . '=' . $value . '&';
	}
	rtrim($fields, '&');
	$post = curl_init();
	curl_setopt($post, CURLOPT_URL, $url);
	curl_setopt($post, CURLOPT_POST, count($data));
	curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
	curl_setopt($post, CURLOPT_RETURNTRANSFER, 1);
	
	// I tried adding this below with no luck... 
	//curl_setopt($post, CURLOPT_HTTPHEADER, array ('Content-Type: text/html, charset=utf-8'));
	
	$result = curl_exec($post);
	curl_close($post);
}

//Brochure Request
if($form["id"] == 1){
	
	$data = array(

		'first_name' => rgar( $entry, '1' ),
		'last_name' => rgar( $entry, '2' ),
		'company' => rgar( $entry, '3' ),
		'address' => rgar( $entry, '4.1' ),
		'city' => rgar( $entry, '4.3' ),
		'provinces_states' => rgar( $entry, '4.4' ),				
		'zip' => rgar( $entry, '4.5' ),
		'country' => rgar( $entry, '4.6' ),
		'phone' => rgar( $entry, '5' ),
		'email_address' => rgar( $entry, '6' ),	

	 );
	post_to_url("https://mydatabase.com/external_requesthandler.lf", $data);
}

}

Does anyone have a workaround or am I missing something?
