Subject: printable characters
I have the regex
my $regex = qr/^([\w `^~!@;:,+%&|<>{}()=\-\$\*\?\[\]\\\.\/\'"#]*)$/;
for matching the printable characters `^~!@#$%&*?_+-={}[]()<>;:'"|\,./
a..z A..Z 0..9
is there any better approach ?

"printable" whitespace, and [[:graph:]], which does not.
See 'perldoc perlrecharclass' for other forms.

Use the class [[:print:]]
Oh, and no, you don't need modules for this.
