When you 'cat' this page, it is well displayed.
But when with less, there is question marks replacing some characters.

For me still, some characters are printed with question marks 

rpm -q less
less-678-1.mga9

Confirm result from katnatek: current version 632 and update 678 behave exactly the same way.

env|grep LESS
LESSCHARSET=koi8-r
...

However, it should be LESSCHARSET=utf-8

It is provided that the variable is set through a script /etc/profile.d/20less.sh [1]
Sourcing it let the env variable correctly.
Thus the problem is that when the script is sourced, locale is not yet defined.

How to fix that?

This change the file 20less.sh which now avoid to define env variable LESSCHARSET. I checked that it is no more defined in Fedora without issue.
I also added a double | in LESSOPEN according to https://bugzilla.redhat.com/show_bug.cgi?id=1254837

More information on package less-678-1.1.mga9.x86_64
This version of less includes lesspipe.sh from Wolfgang Friebel
( https://www-zeuthen.desy.de/~friebel//unix/less/ ).

This enables you to view gz, bz2, lzma, zip, rpm and html files
among others with less. It works by setting the LESSOPEN 
environment variable, see the man pages for details.

If you want to disable this behavior, either use 'unset LESSOPEN' or
use an alias ( alias less='less -l' ).

less will open html files with lynx, then html2text, then cat if
none of the previous were found.

Need close and start session again to really make effect
Now the russian manual attached is clearly displayed without ? marks

As I say in my test you have to close
session an star session again
If not the env variable is still present

Russian man pages are displayed incorrectly in the terminal "konsole", "terminator", etc.:
- question marks instead of letters, — " исследования сети и проверки безопасност��. ", there is no pattern
- violation of indentation boundaries in the text
- the letter " Л " is not displayed, — " ОПРЕДЕЕНИЕ ЦЕИ СКАНИРОВАНИЯ " (it should be " ОПРЕДЕЛЕНИЕ ЦЕЛИ СКАНИРОВАНИЯ ")

If you give the command " man nmap > ~/Text_nmap_RU.txt " , then all the text in the file will be correct.

After giving the command "unset LESSCHARSET" in the "konsole" terminal, and then immediately giving the command "man nmap", the terminal works correctly, only 1 time. That is, it is necessary to give the command "unset LESSCHARSET" every time before launching "man nmap" (or another "man_RU").

In the ROSA distribution, the "man nmap" command works correctly, and the text in the terminal is written correctly.

После обновления пакета до версии less-678-1.1.mga9 (из репозитория "Core Updates Testing"), все русские "man_RU" в терминале стали отображаться корректно.
