What potential issues can arise when sending special characters from an Android keyboard to PHP?

Special characters from an Android keyboard may not be encoded properly when sent to a PHP server, leading to encoding issues or data corruption. To solve this problem, you can use the `utf8_encode()` function in PHP to convert the incoming data to UTF-8 encoding, ensuring that special characters are handled correctly. 

// Convert incoming data to UTF-8 encoding
$data = utf8_encode($_POST['data']);

// Now you can safely use the $data variable in your PHP code
