* The Problem

$ perl -e 'print chr(0x00F6)'
?% $ perl -e 'print
chr(0x4396)'
Wide character in print at -e line 1.
�%

Where chr(0x00F6) should be ö and it is printed properly by Python or Perl
6 on my env so I infer that it is an issue about Perl.

* Version Info

$ perl -v

This is perl 5, version 26, subversion 2 (v5.26.2) built for
darwin-thread-multi-2level

If you add the -C option, it works properly

perl -C -e 'print chr(0x00F6)'
ö

What I suspect is happening is that your terminal is set up for UTF-8 text. Perl is printing the F6, but that is illegal UTF-8, and so your terminal doesn't handle it as one might expect. Perl doesn't know what your terminal is set up for. Specifying the -C tells it.

With -C, perl converts the F6 to its UTF-8 representation before printing.

The reason anything above 0xFF does print correctly is that it can't possibly be represented by a single byte, and so Perl converts it to UTF-8, and your terminal is happy. But you get the wide character warning indicating that Perl expects your terminal to not be able to handle UTF-8.

I don't know why the other tools seem to work here.

Can you detail what happened when your perlbug failed?

No response from OP. This ticket is not a perl issue.
