jTSS takes whatever the client passes in.

See JTpmTools optional parameters:
  -e encoding    ... encoding for password strings (legal values: ASCII, UTF-16,
                     UTF-16BE, UTF-16LE) (default: UTF-16LE)
  -n             ... append null termination to password strings


There is/was confusion about encoding of passwords in the 1.1 vs 1.2 spec
vs. "reality" of various Windows stack vendors.
In order to offer the user the choice, JTpmTools supports above flags to allow
maximum compatibility (see source code how to handle the cases).

I hope this is also your "Authentication" issue in your mail of 2007-07-04 18:44.
