Hi Joel,

I don't know about Fox and its registry but you could try to avoid 
null chars by using a base64 encoding for the marshalled strings, 
something like

  s = [ Marshal.dump( my_object ) ].pack( 'm' )

These strings don't include null or other special characters. To get 
the marshalled object back you would do

  my_object = Marshal.load( s.unpack( 'm' )[ 0 ] )

HTH
