Not all codepoints are equally likely. That's the whole point behind
variable-length encodings like Huffman compression (eg deflation as
used in zip/gzip), UTF-8, quoted-printable, and Morse code. They
handle a sub-range efficiently and the rest of the range less
efficiently.

I propose, then, that we abolish files. Who *knows* how many different
things might be represented in a file! We need a single coding scheme
that can handle everything, without changing representation. This
ridiculous state of affairs must not go on; the same representation
can be used for bitmapped images or raw audio data!
