I can't reproduce this error (with zsh-5.9-271-ge4e9afe) on
  5.15.0-75-generic #82~20.04.1-Ubuntu
or
  6.2.0-33-generic #33~22.04.1-Ubuntu.

I guess wctomb() behaves differently on your Ubuntu. What do
you get by running the following C code? On my Ubuntu I get -1.

# On my Mac I get 1, but wctomb() is not used on macOS since
# __STDC_ISO_10646__ is not defined.


#include <stdio.h>
#include <locale.h>
#include <stdlib.h>

int main()
{
	char buf[MB_CUR_MAX];
	setlocale(LC_ALL, "C");
	printf("%d\n", wctomb(buf, 0x80));
	return 0;
}
