Ncurses 6.3 has been released two days ago:
https://www.invisible-island.net/ncurses/announce-6.3.html
The wide background issue is mentioned in the release notes:
These are improvements to existing features:
- provide for wide-characters as background character in wbkgrnd
I've built and (cursorily) tested the new release, everything works as expected, so I'm closing the issue. Enjoy!

Hello, I have removed the % prefixes today, so that the ncurses system can be used separately with the package as a prefix.
The bug you have there should not happen, there are no function calls with % prefixes left. Can you please check whether this is an issue with your .cache/common-lisp?
Which file causes the newwin error?
The file src/window.lisp is not loaded by the asd file, it is an old file that I have not yet removed.
Is this last call needed? If yes i wonder which locale is set for the lisp version of the program.
Yes, the call to setlocale is absolutely needed in C. In lisp, it is inherited from the shell from which the sbcl executable is called, so sbcl calls setlocale when started.

Sorry, I can not say why your asdf:make goes wrong. I usually ql:quickload the systems directly from the quicklisp/local-projects directory. Maybe asdf:make does something different. I cloned the repository to check and do not see the newwin error. You can see that newwin is exported in the ncurses/package.lisp file.

Yes, the blank screen is also what I get. Thanks for reproducing the bug. I have brought this up on the ncurses mailing list, it seems to be a known issue.

My guess is that it is entirely on the C side, because the wbkgrnd routine has been substantially changed between ncurses 6.1 and 6.2. I have contacted the author of ncurses, and he is looking into it at the moment.
Thanks for reproducing the bugs, this helps very much. Until others confirm, you can never be sure that you haven't caused the bug yourself and are unaware of it.

As far as I can confirm, the wbkgrnd bug has been fixed with the recent patch ncurses-6.2-20210206:
https://github.com/ThomasDickey/ncurses-snapshots/releases/tag/v6_2_20210206
Arbitrary unicode characters can be set as window backgrounds again.
Unicode test ut05 should work now as it did previously with ncurses 6.1:
Line 131 in 89ecd14
The patch will likely be part of the upcoming ncurses 6.3 release.
