Well, not strictly true.  Or at least, Unicode text is not quite 
stateless.  We have these directional overrides and embeddings and 
isolates... The embeddings can even be nested.  And turning national 
digit shaping on and off, etc.  Statelessness looks more like an ideal; 
the current reality already violates it.
