To convert a string to characters one can use split based on the empty regex,
That should be "a pattern matching the empty string".
The "empty regex" works differently:
perl -wle '
my $text = "abcdefghi";
$text =~ /[aeiou]/;
$text =~ /x/;
my @result = $text =~ //g;
print "@result";
'
a e i
(admire how 'regex' and 'regular expression' are avoided in perldoc -f
split)
