Do we want to standardize anything besides unicode?

IMO, no. In fact, I'd only standardize UTF8.

Subject: [SG16-Unicode] Namespaces

Ranges has made a precedent that we can provide better versions of old
functions by putting them into a separate namespace. It is general
consensus that almost all current text related function are obsolete. We
should consider a namespace for new ones.

I think std::text fits this. This namespace would contain functions that
are modern and can properly support Unicode (and other encodings!).

There is also a precedent of my proposal and D1628 having separate
namespace specifically for Unicode. Generally speaking, Unicode is a
subset of text processing so in mathematical sense it would be obvious
to put unicode namespace as std::text::unicode but here I agree that it
is too much typing.

So I propose the following:

std::text for general purpose text algorithms (to be determined as we
haven't even nailed the Unicode yet, but consider std::text::to_upper,
std::unicode for Unicode classes and algorithms. Everything in std::text
should be able to work with classes from std::unicode.

Then we can add more encodings under std or maybe right into std::text
if they are too simple.
