--- Definitely not, unless those are nulls, clusters of nulls or some 
embellishments. But that would mean the additional "encoding" which I hate to 
contemplate, since even without it we have a hard case to crack .-)

Right you are and spaces may be either: a) spaces, but all in wrong places 
(pardon the rhyme),  or b) original spaces can be all deleted, letters shuffled 
and  interposed by spaces functioniing as  "nulls". regards,
