How do I read such malformed strings in perl with unicode support enabled without having it dying?

If you don't like how the decoding layer handles error, you are free to perform the decoding yourself. Encode's decode's third argument controls how it behaves on error.

But the solution to the problem is to avoid generating the garbage in the first place.

$_->{info}{name} is a string that consists of the characters 43.72.79.73.69.73.AE. It's apparently a string of decoded text (a string of Unicode Code Points).

But file handles can only transmit bytes. You need to encode the Unicode Code Points into bytes to write them to a file handle.

One way of doing this is to add an encoding layer to the file handle. 

perl -gne'
   use v5.36;
   use utf8::all;
   use Bencode qw( bdecode );
   say bdecode( $_ )->{info}{name};
