Fix a torrent file encoding

Published on

Sometimes, when you open a torrent file, the non-Latin letters in the file names will appear garbled. Apparently, some programs write the utf-8 name in the field path.utf-8 and write the field path in some other encoding.

I wrote a small Perl script that fixes such torrent files by copying the path.utf-8 field into the path field. To fix the torrent file:

  1. Download the script.

  2. Make sure you have Perl installed.

  3. Install the Bencode Perl module.

    E.g. on Fedora, you can run dnf install perl-Bencode.noarch.

  4. Run

    perl my_broken_file.torrent new_fixed_file.torrent

    and new_fixed_file.torrent will be created.
