Thanks Paulo and Norbert,

I must debug better on my side, as all I observed was that normal
behaviour for "tlmgr help" came from removing "/opt/local/bin" from
PATH. 

So perhaps other binaries are involved in this PATH setting.

When I quit the good-looking tlmgr doc wI find this  was printed to my Terminal:

----
$ tlmgr help
You have an old groff. Update to version 1.20.1 for good Unicode support.
If you don't upgrade, wide characters may come out oddly.

 at /opt/miniconda3/lib/perl5/5.18.2/Pod/Perldoc.pm line 1346.

However when I quit the bad-looking help I see nothing in my Terminal window.

Other difference is that at top of displayed help I see in "good" case

-----
TLMGR(1)              User Contributed Perl Documentation             TLMGR(1)
-----
then a few blank lines,

which does not show in "bad case"

and at bottom there is 

----
perl v5.18.2                      2017-09-01                          TLMGR(1)
(END) 
----

but only (END) in "bad case"

When I issue "man -d tlmgr" there is no difference
in output in both contexts, but this is possibly completely
irrelevant.

Best
