This doesn't seem right. I understand from [1] that the primary ASCII-
compatible encoding on z/OS is ISO-8859-1, not UTF-8.

man-db relies on groff, and consists of several programs. It's likely that
one of these programs needs a modification.

Does "groff -Tutf8 -mandoc man7/groff_char.7 | less -R" (in a UTF-8 console)
produce good-looking output? If yes, then the problem is likely in the man-db
package, otherwise in the groff package.
