Currently, we are using unibyte buffers for various internal operations (e.g rmail, tar-mode, jka-compr, ...). It is theoretically possible to modify all of them to use a multibyte buffer that contains only ASCII and eight-bit chars. But, as it may make the operations slow, I don't see a merit in doing that.
