What considerations should be made regarding encoding and character sets when sending Telnet commands via PHP?

When sending Telnet commands via PHP, it is important to ensure that the encoding and character sets are properly handled to avoid any issues with special characters or incorrect data transmission. One way to address this is by setting the encoding to ASCII when sending Telnet commands using PHP's socket functions. 

// Set the encoding to ASCII
ini_set('default_charset', 'ASCII');

// Create a socket connection to the Telnet server
$socket = fsockopen('telnet.example.com', 23);

// Send a Telnet command
fwrite($socket, "command\r\n");

// Close the socket connection
fclose($socket);
