That would be helpful, yes.  I expect it will work on Linux.

It is not clear whether this is a problem encoding or decoding.  Can
you try this on NT:
  type (thefile) | gpg -o output.gpg --encrypt 

If that doesn't work:

  type (thefile) | gpg -o output.gpg -z0 --encrypt

That is, try piping the data in rather then giving the filename on the
command line.  Then, try decrypting the output.gpg file via both:

  gpg -o result output.gpg
and
  type output.gpg | gpg -o result
