iconv - different output on Linux

[Pascal Christen]

Hi

I have a problem with iconv (libc) or maybe it's by design on BSD:

FreeBSD11.2:
[test at server:~] % echo 'Ørnæréjö' | iconv  -f utf-8 -t ascii//TRANSLIT
Ornaer'ej"o

macOS Mojave:
Pascals-MBP:~ pascalchristen$ echo 'Ørnæréjö' | iconv  -f utf-8
-tascii//TRANSLIT
Ornaer'ej"o

Ubuntu 18.04:
test at DE-NUE01 ~ # echo 'Ørnæréjö' | iconv  -f utf-8 -t ascii//TRANSLIT
Ornaerejo


As you can see, on BSD some characters are with ' or " and on Linux it's
just as expected when using TRANSLIT. Any ideas?


Greetings Pascal
