[split] Verbose cipher?

[MarcoP]

I'll quickly come up with a concrete example. Say that for some reason they assigned plaintext "o" to EVA-y. Now, EVA-y is a glyph with a "swoop", so it feels "end of word" to the scribe, so they leave a space. Like that, the scribe introduces a verbose system where [o] is turned into [y_], without actually having the mental concept of space as a character.

I am not sure I understand. If the space after 'y' is not significant, it can be ignored, it is in fact a null; if _ does not add any information to that encoded by 'y', the cipher is not verbose.
