Hej Holger!

 HG> OK, the divide sign on the numerical keypad is a dash with dots
 HG> above and below the dash.

On my keyboard it is the '/' character but I've seen some keyboards that use 
that divide sign.  I see it as F6 or dec.246 in CP850.  That translates to the 
'÷' character in utf8 - usually written as U+00F7 or \u00f7 in bash.

-={ ':read !echo -e "\u00f7"' starts }=-
÷
-={ ':read !echo -e "\u00f7"' ends }=-

Gotta love bash ... and vim in this case but the same will happen on a bash 
commandline without vim by just typing; echo -e "\u00f7"

You're welcome.

 HG> Correct, but so far I can't recall having seen that letter in a

It isn't a character in Dansk.  If you look at the kludges in my reply to you 
it is Swedish (sv_SE.utf8) whereas in my replies to Benny are in Dansk 
(da_DK.utf8).  Also the taglines are different other than the 'Møøse' part 
which is neither Swedish or Dansk.  It is a bogus word for moose which requires 
the Norwegian slashed small 'o' characters to enhance the taglines.  That will 
always be the same no matter what language.  For example in German it would be 
"Ein Møøse hat meine Schwester einmal gebissen ..." while in Ukrainian it 
would be "А Møøse колись кусав мою сестру ...".  So the 
samll angstrom is in the tagline below simply because I am replying to you and 
replies to you from the raspi3b+ will contain Swedish characters while to Benny 
they will be Danish characters.  It is the way I configured it ... for now.

Livet är gott,
Maurice
