in thread How to Fix Character Encoding Damaged Text Using Perl?
Thank you very much, moritz, for your helpful reply. I greatly appreciate it.
So, what did you try?
I tried variations of something very similar to your second example using Encode::Repair::learn_recoding(). In hindsight, I believe the problem that thwarted my efforts was my inclusion of use utf8 in the script. Needless to say, I thought I was doing the right thing when, in fact, I was doing exactly the wrong thing.
I just tested using Encode::Repair to repair damaged text that has non-ASCII characters in it.

It works! Here's the script.
use v5.16; use Encode::Repair qw( repair_encoding ); while (my $damaged_text = <DATA>) { chomp $damaged_text; my $repaired_text = repair_encoding( $damaged_text, [ decode => 'UTF-8', encode => 'UCS-2LE', ] ); say $repaired_text; } exit 0; __DATA__ 敒›剕䕇呎 敌馀潧琠韦겜鯥↽
Brilliantly, this prints…
Re: URGENT Let’s go to 日本国!
Notice, however, that I had to remove binmode STDOUT, ':encoding(UTF-8)'. This version of the script also works.
use v5.16; use Encode qw( decode ); use Encode::Repair qw( repair_encoding ); binmode STDOUT, ':encoding(UTF-8)'; while (my $damaged_text = <DATA>) { chomp $damaged_text; my $repaired_text = repair_encoding( $damaged_text, [ decode => 'UTF-8', encode => 'UCS-2LE', ] ); say decode('UTF-8', $repaired_text); } exit 0; __DATA__ 敒›剕䕇呎 敌馀潧琠韦겜鯥↽
I can study and study and study the Perl documentation, but I'll never grok the subtleties of Perl's Unicode model. It's simply too profoundly confusing for me.
I love your module, moritz! Thanks for it, and for your help here.
