It's probably a case of double-encoding.

"Å" encoded using UTF-8 and then encoded using UTF-8 a second time would appear as "Ã" (followed by a control character) on an terminal expecting UTF-8.

For example, the following produces something that looks like "Ã□" on my terminal:

perl -e'
   use open ":std", ":encoding(UTF-8)";
   use utf8;
   use feature qw( say );
   $_ = "Å";
   utf8::encode($_);  # XXX Bug. Already handled by ":encoding".
   say;

In context, this would indicate that $item->{ows_Justification} contains text encoded using UTF-8 rather than decoded text as one would expect.
