Also confirming that your code does indeed work.

Your test case doesn't have simple [something] in it. If you are willing to delete all of the brackets, not just the double ones, then a shorter more simple, tr statement can be used. Tr is in general faster than a regex with substitution and because its features are so limited, there is no need to escape the characters, so the expression is more readable. 

use warnings;
use strict;

my $doc = q('C-3PO' or 'See-Threepio' is a humanoid robot character fr
+om the [[Star Wars]] universe who appears in the original ''Star Wars
+'' films, the prequel trilogy and the sequel trilogy.);

$doc =~ tr/[]'//d;

print "$doc\n";

__END__

C-3PO or See-Threepio is a humanoid robot character from the Star Wars
+ universe who appears in the original Star Wars films, the prequel tr
+ilogy and the sequel trilogy.
