set crypt = Server.CreateObject("Chilkat.Crypt2")

' 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)
Response.Write "<pre>" & Server.HTMLEncode( "iso-8859-1:") & "</pre>"
Response.Write "<pre>" & Server.HTMLEncode( qp) & "</pre>"
decoded = crypt.DecryptStringENC(qp)
Response.Write "<pre>" & Server.HTMLEncode( decoded) & "</pre>"

' 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)
Response.Write "<pre>" & Server.HTMLEncode( "utf-8:") & "</pre>"
Response.Write "<pre>" & Server.HTMLEncode( qp) & "</pre>"
decoded = crypt.DecryptStringENC(qp)
Response.Write "<pre>" & Server.HTMLEncode( decoded) & "</pre>"
