Lipogrammatic text

[MarcoP]

MarcoP - would it be possible to arbitrarily add a couple of characters (representing, I dunno, two vowels that would have been removed in the lipogramatic text - we would have to calculate the normal appearance ratio of the character) to the VMS text  and re-run the test?

I don't know. When looking at Perec's text, it seems to me that Koen is right and that it is statistically undistinguishable from "normal" French. I have no idea of how it would be possible to re-introduce 'e' without going into the details of the language: I think it's something that could only be done manually by a French native speaker or maybe via software by an advanced AI.
