#  Here's a string in Icelandic using non us-ascii chars:
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")
qp = crypt.encryptStringENC(s)
print "iso-8859-1:" + "\n";
print qp + "\n";
decoded = crypt.decryptStringENC(qp)
print decoded + "\n";

#  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)
print "utf-8:" + "\n";
print qp + "\n";
decoded = crypt.decryptStringENC(qp)
print decoded + "\n";
