Maybe he is arguing for a higher-level approach to text representation. Text
is, after all, an important enough application field that it deserves some
treatment in a standard library. Unfortunately (as we are all bearing
witness to in this discussion) there is no standard way to do it, even for
one (natural) language, much less all of them.

This is getting a little afield from the topic of the list, but I have been
wondering if maybe Unicode (and other related standards) might not end up
being most valuable in the long run, not for being able to represent text
from existing languages but, for shaping the form of languages to come. I
don't mean completely new languages of course (I think I heard Klingon and
Tengwar were actually submitted for inclusion!), but rather that as
electronic information becomes more and more central to communication, the
need to encode it will change the way people speak and write in other media
as well. I think this is happening already, sort of: for example, I've seen
email emoticons used in published materials, and on billboards here in
Japan; and we all know a hundred words from computer jargon that have made
it into mainstream languages.

That's exactly the way I think of and use O'Caml characters and strings. It
is sort of unfortunate that O'Caml inherited this terminology from C... I
would have preferred "byte" or "octet" for characters, at least.
