Hej Holger!

 HG> Well I can't give you a better translation than the ones I gave.
 HG> They are solely based on your german tag line.

Okay we're back to the Swedish raspi3b+ version of my replying thingy and have 
switched the tagline back to "Don't cry for me I have vi" as it contains both 
angstrom (c3 a5 = U+00E5) the double dotted 'o' character (c3 b6 - U+00F6).  No 
Møøse were harmed in the making of it ... not to mention my sister.

In German I show;

-={ ':read !trans -b -no-ansi -s english -t german "Don't cry for me I 
have vi."' starts }=-
Weine nicht um mich, ich habe vi.
-={ ':read !trans -b -no-ansi -s english -t german "Don't cry for me I 
have vi."' ends }=-

Looks good so far except no multibyte characters.  Everything is ascii.  Now 
the reverse;

-={ ':read !trans -b -no-ansi -s german -t swedish "Weine nicht um mich, 
ich habe vi."' starts }=-
Gråt inte för mig, jag har vi.
-={ ':read !trans -b -no-ansi -s german -t swedish "Weine nicht um mich, 
ich habe vi."' ends }=-

Other than the addition of the comma it looks perfect from this angle.  Now 
let's bring it back to English;

-={ ':read !trans -b -no-ansi -s swedish -t english "Gråt inte för mig, 
jag har vi."' starts }=-
Don't cry for me, I have we.
-={ ':read !trans -b -no-ansi -s swedish -t english "Gråt inte för mig, 
jag har vi."' ends }=-

Not too bad other than the 'we' which should still be 'vi' since it is the name 
of a program that is the same in all three languages.  Going straight from 
English to Swedish produced the tagline shown below and 'vi' remains intact.  
Mind you the same happens in English to German but adds a comma.  Without 
knowing for sure the tagline looks to be the most correct translation.  What do 
you think?

Livet är gott,
Maurice
