That's simple to try .. I suspect you didn't try it.
tab@music3:~/2018-0717$ cat pm.pl
#!/usr/bin/perl
use strict;
use warnings;
{
my $word = '$-.%';
my $new_word = join ( '', map { "[$_]" } split '', $word );
print "$word -> $new_word\n";
}
tab@music3:~/2018-0717$ perl pm.pl
$-.% -> [$][-][.][%]
tab@music3:~/2018-0717$
Perl doesn't care what's in the string -- more specifically, split doesn't have problems with any characters that may have special meaning in a regex.
