I've recently spent some time adding multibyte support to the coreutils
text processing tools (sort, uniq, join, tr, cut, paste, expand, unexpand,
fmt, fold, and pr) in this repository:

First of all, thank you for working on this!
Multibyte support in coreutils is indeed an ongoing effort,
and any help is appreciated.
Before I put any more work into cleaning up my branch, I also have a
general development question: Is it OK to make multibyte additions to the
lib directory here, or do those changes need to made in an upstream
repository or in the applications themselves?
To move forward, I would suggest the following:
1.
Base your work on the coreutils GIT repository instead of the
coreutils-8.28 tarball (version 8.29 was just released).
A good starting points are:
https://git.savannah.gnu.org/cgit/coreutils.git/tree/README-hacking
https://git.savannah.gnu.org/cgit/coreutils.git/tree/HACKING
2.
Regarding "lib" directory:
When using the coreutils git repository (and running "./bootstrap"),
it will automatically clone the gnulib git repository
as a git-submodule. Then, any changes you make under "lib"
will be tracked against the "gnulib" git repository (which is,
as you've said, a separate upstream project).
3.
GNU coreutils requires copyright assignment for major code contributions.
To learn more, see: https://www.gnu.org/licenses/why-assign.html
It'll be good to start the copyright assignment process by filling this
form:
https://git.savannah.gnu.org/cgit/gnulib.git/tree/doc/Copyright/request-assign.future
Please enter both "COREUTILS" and "GNULIB" as the projects/packages in
the form to ensure you can contribute to both.
Completing the copyright assignment early ensures we can safely
incorporate any future patches you send.
4.
If you wish to also experiment with the other multibyte effort,
the following commands should be used:
git clone git://git.sv.gnu.org/coreutils.git
cd coreutils/
wget
https://files.housegordon.org/src/coreutils-multibyte-2017-12-23.patch.xz
unxz coreutils-multibyte-2017-12-23.patch.xz
git am < coreutils-multibyte-2017-12-23.patch
./bootstrap
./configure
make
5.
Past discussions mentioned on
https://crashcourse.housegordon.org/coreutils-multibyte-support.html
have some good points and recommendations about
implementation details and requirements.
