Re: [KEYPROV] SASL stringprep Was: FW: New Version Notification - draft-ietf-keyprov-dskpp-13.txt

Phil,

It seems that your request for SASL stringrep was honored in DSKPP
so this is not a topic anymore.

 > You know of a token where you can input unicode sequences direct?

In SKS/KeyGen2 all string data is assumed to be in UTF-8 which can be
inputted from any computer and which has a defined byte-representation.

So yes, SKS tokens *do* Unicode although they do not really know
what Unicode is.

If UTF-8 doesn't work with Chinese, Arabic, or Japanese without an
extra layer of interpretation it IMO means tha  "XML failed" since it
by default is supposed to be coded in UTF-8.
