And it seems to me that that is *very* unlikely to happen, precisely
because ρ is so deeply embedded in the array and vector logic of APL.
That is counting the data size of arrays of "characters" (i.e., code units).
If somebody tried to somehow teach ρ to do something different
about characters, changing the concept of array of code units into
something more akin to what we think of as Unicode strings, that
would end up being a *different* language -- not APL!
