'  Here's a string in Icelandic using non us-ascii chars:
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"
qp = crypt.EncryptStringENC(s)
outFile.WriteLine("iso-8859-1:")
outFile.WriteLine(qp)
decoded = crypt.DecryptStringENC(qp)
outFile.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"
qp = crypt.EncryptStringENC(s)
outFile.WriteLine("utf-8:")
outFile.WriteLine(qp)
decoded = crypt.DecryptStringENC(qp)
outFile.WriteLine(decoded)
outFile.Close
