I'm not sure what I have. The file definitely has an invisible character in it. When I copy and paste the file name:

Works:

perl -wMstrict -lE "qq/Screenshot-2024-02-23-at-1.05.14 AM.png/ =~ /A/ + and say 'OK' or die"

Doesn't work:

perl -wMstrict -lE "qq/Screenshot-2024-02-23-at-1.05.14 AM.png/ =~ /\s +/ and say 'OK' or die"

The character between the "4" and "A" is the invisible character.

$PM = "Perl Monk's";
$MC = "Most Clueless Friar Abbot Bishop Pontiff Deacon Curate Priest Vicar Parson";
$nysus = $PM . ' ' . $MC;
