Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

// Here's a string in Icelandic using non us-ascii chars:
string s = "Ég get etið gler án þess að meiða mig.";

crypt.CryptAlgorithm = "none";
crypt.EncodingMode = "quoted-printable";

// Quoted-printable encode/decode the iso-8859-1
// representation of the string.  Notice how each
// Icelandic char is represented by 1 byte:
crypt.Charset = "iso-8859-1";
string qp = crypt.EncryptStringENC(s);
Debug.WriteLine("iso-8859-1:");
Debug.WriteLine(qp);
string decoded = crypt.DecryptStringENC(qp);
Debug.WriteLine(decoded);

// Now do the same using utf-8. Notice how each
// Icelandic char is represented by 2 bytes in utf-8:
crypt.Charset = "utf-8";
string qp = crypt.EncryptStringENC(s);
Debug.WriteLine("utf-8:");
Debug.WriteLine(qp);
string decoded = crypt.DecryptStringENC(qp);
Debug.WriteLine(decoded);
