I'm arguing about non-compressed, eventually padded data types that make learning Unicode (or any other applicable data format) easier because of the equivalence : 1 atomic unit ("character", pixel) = 1 smallest addressable unit of memory (byte). This involves byte size being at least as large as atom size.

And it's particularly important to have this property for text, because not only data is overwhelmingly stored as text (in importance, not by "weight"), but because computer programs themselves are written using text.
