So which character encoding on STDOUT does perl use by default? That should
be utf-8 without any further ado, shouldn´t it? When I add
binmode STDOUT, ":encoding(utf-8)";
the characters are displayed correctly in the terminal. Why would perl use
something else than utf-8 by default?
Take the following with a grain of salt. My knowledge is mostly
hearsay and supposition with a dash of cargo cultism on this matter.
Perl predates even Unicode (they both came out in '87). Unicode did
not get much traction until the mid-nineties when people started
realizing that UTF-8 (created in '92) was a good thing. So, for most
of its early history, Perl used Latin1. It still does to a large
extent for backwards compatibility reasons. To make Perl 5 a proper
UTF-8 environment there are a number of knobs to pull and buttons to
poke.
You may find this video from YAPC NA 2016 enlightening:

Also, this answer on StackOverflow by tchrist (Tom Christiansen, who I
would say knows the most about the intersection of Perl and Unicode)
is a good resource: http://stackoverflow.com/a/6163129/78259
Hope this helps.
Thanks! That makes it really complicated to write applications which display
data from a database via a web browser --- yet ppl are doing this since a pretty
long time now. But no matter what I do, Umlaute are not displayed correctly
throughout the whole web page: they are either wrong in the data from the
database or in print statements or in the output of the CGI::FormBuilder.
There´s probably no way to get it right :(
