echo $sb->GetEncoded('hex', 'iso-8859-1'), "\n";

// If encoded to hex using the utf-8 charset,
// each é char is represented in 2 bytes.
// Output: C3A920C3A920C3A9
echo $sb->GetEncoded('hex', 'utf-8'), "\n";

// Here's utf-16
// Output: E9002000E9002000E900
echo $sb->GetEncoded('hex', 'utf-16'), "\n";

// utf-32
// Output: E900000020000000E900000020000000E9000000
