From module@renee-baecker.de

quoting from perl5100delta (
http​://perldoc.perl.org/perl5100delta.html#Miscellaneous )​:

The -C option can no longer be used on the #! line. It wasn't working
there anyway, since the standard streams are already set up at this
point in the execution of the perl interpreter. You can use binmode()
instead to get the desired behaviour.

Hi,

attached is a small documentation patch that adds a hint that -C can no
longer be used in the shebang to perlrun.

Cheers,
Renee

This is not a bug in perl, it’s a bug in your shebang line. The
fact that this used to work was a bug in perl that has since been
fixed. The correct incantation for what you want to achieve is

  use open qw( :std :encoding(UTF-8) );

This is not a bug in perl, it???s a bug in your shebang line. The

fixed. The correct incantation for what you want to achieve is

use open qw\( :std :encoding\(UTF\-8\) \);

It's not a bug in that it's behaving as documented.
But, arguably it is a bug, because it could be made to work in future.
There hasn't been the conjunction of people with desire, ability and time.

I have some idea how it might be made to work, if someone else with time
wants to learn enough to get it done.
