What are the differences between using rawurlencode and utf8_encode to address special character issues when sending textarea data with cUrl in PHP?

When sending textarea data with cUrl in PHP, special characters may cause issues if not properly encoded. One way to address this is by using rawurlencode, which encodes special characters in the data. Another option is to use utf8_encode, which converts a string to UTF-8 encoding. Both methods can help ensure that special characters are properly handled when sending textarea data with cUrl in PHP. 

// Using rawurlencode to encode special characters
$data = rawurlencode($_POST['textarea_data']);

// Using utf8_encode to convert string to UTF-8 encoding
$data = utf8_encode($_POST['textarea_data']);
