How can PHP developers troubleshoot and resolve issues with special characters in emails?

Special characters in emails can cause encoding issues if not handled properly. PHP developers can troubleshoot and resolve these issues by ensuring that the email content is properly encoded using functions like utf8_encode() or htmlentities(). Additionally, setting the proper headers for the email content type can help avoid encoding problems.

// Example code snippet to handle special characters in emails

// Encode the email content
$emailContent = utf8_encode($emailContent);

// Set the proper headers for email content type
$headers = "Content-type: text/html; charset=utf-8";

// Send the email
mail($to, $subject, $emailContent, $headers);
