No text, but a visual code

  If a group of glyphs represents a word, whether in a natural or encrypted language, I wonder what the point is of finding a single glyph afterward, and then another word and another single symbol. And a succession of words followed by a succession of single symbols. Does that make any sense? Isn't it more reasonable to think of symbols full of meaning that come together or that can function on their own?

It could very well be that they are numbers. The fact that there are no numbers in the VM (apart from the folio and quire numbers, and the numbers on f49v) when it was extremely common for manuscripts at the time to have them (especially astrological ones) should tell us something about what these individual glyphs might mean. I don't think your option necessarily excludes the other, i.e. you could have "symbols full of meaning" in themselves (such as astrological notation, gradients, numbers etc...) intertwined with a different encoding system. I mean it has already been shown how labelese and the rest of the VM behave very differently. Whether that's the result of a separate encryption procedure or of the underlying properties of the encrypted text (and this is assuming it is an encrypted text), we can't really say, but speculation never hurt anyone
