in reply to How to sanely handle unicode in perl?

Switching to binmode and manually picking the encoding from the $ENV seems to work for me:
#!/usr/bin/perl use strict; use warnings; open my $in, '-|:encoding(utf8)', "echo \xc3\xb6" or die $!; my $enc = $ENV{LC_ALL}; $enc =~ s/.*\.//; # TODO: en_US with no encoding not handled. binmode STDOUT, "encoding($enc)"; my $line = <$in>; chomp $line; print "I read a line, that is ", length $line, " chars long.\n"; print "That line is: $line\n"; $line =~ s/\x{f6}/o/; print "That line in ascii is: $line\n";

Update

It seems all that's needed in your original code is to remove the local encoding from the input:
open my $in, '-|:raw:encoding(utf8)', "echo \xc3\xb6" or die $!;

    Thanks. With ":raw" prepended it works just like it should.

    Fantastic!
