    //  Any string argument automatically begins the 30-day trial.
    bool success;
    success = crypt.UnlockComponent("30-day trial");
    if (success != true) {
        printf("%s\n",crypt.lastErrorText());
        return;

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

    crypt.put_CryptAlgorithm("none");
    crypt.put_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.put_Charset("iso-8859-1");
    const char * qp;
    qp = crypt.encryptStringENC(s);
    printf("iso-8859-1:\n");
    printf("%s\n",qp);
    const char * decoded;
    decoded = crypt.decryptStringENC(qp);
    printf("%s\n",decoded);

    //  Now do the same using utf-8. Notice how each
    //  Icelandic char is represented by 2 bytes in utf-8:
    crypt.put_Charset("utf-8");

    qp = crypt.encryptStringENC(s);
    printf("utf-8:\n");
    printf("%s\n",qp);

    decoded = crypt.decryptStringENC(qp);
    printf("%s\n",decoded);
