First, I'm pretty sure a / cannot be in a filename. Second, what would you replace the * and ? and " with?

I would approach that like this (GNU tools specific):
Code:
find /targetdir -type f -print0 | xargs -rl0 rename_bad_filename

where rename_bad_filename is a perl script that is executable and in your PATH...
Code:
#!/usr/bin/perl
$newf = $oldf=$ARGV[0];
# replace any non alpha-numeric characters, excluding / . and - with an underscore
$newf =~ s/[^a-zA-Z0-9.\/-]/_/g;
exit 0 if $newf eq $oldf;
print "Renaming \"$oldf\" to \"$newf\"...";
rename $oldf,$newf ;
print ($! ? "Error: $!\n" : "OK\n");

Note: no error checking; existing files are clobbered.

Example output:
Code:
$ rename_bad_filename  2l4kj2l^%.
Renaming "2l4kj2l^%." to "2l4kj2l__."...Error: No such file or directory
$ rename_bad_filename  2l4kj2l.
$ rename_bad_filename  2l4kj2l.\!
Renaming "2l4kj2l.!" to "2l4kj2l._"...Error: No such file or directory
$ rename_bad_filename  \[2-7\]-ldap-reordered
Renaming "[2-7]-ldap-reordered" to "_2-7_-ldap-reordered"...OK

net::ldap::control::relax

Net::LDAP::Control::Relax(3)				User Contributed Perl Documentation			      Net::LDAP::Control::Relax(3)

NAME

       Net::LDAP::Control::Relax - LDAPv3 Relax control object

SYNOPSIS

	use Net::LDAP;
	use Net::LDAP::Control::Relax;

	$ldap = Net::LDAP->new( "ldap.mydomain.eg" );

	$relax = Net::LDAP::Control::Relax->new();

	$msg = $ldap->modify( 'dc=sub,dc=mydomain,dc=eg",
			      changes => [
				replace => { modifyTimestamp => '19700101000000Z' } ],
			      control  => [ $relax ] );

	die "error: ",$msg->code(),": ",$msg->error()  if ($msg->code());

DESCRIPTION

       "Net::LDAP::Control::Relax" provides an interface for the creation and manipulation of objects that represent the "Relax" control as
       described by draft-zeilenga-ldap-relax-03.txt

       The presence of the Relax control in an LDAP update request indicates the server temporarily relax X.500 model constraints during
       performance of the directory update.

       The control is appropriate for all LDAP update requests, including add, delete, modify, and modifyDN (rename) [RFC4511].

       Its criticality is always set to TRUE, and no value.

       There is no corresponding response control.

CONSTRUCTOR ARGUMENTS

       Since the "Relax" control does not have any values only the constructor arguments described in Net::LDAP::Control are supported

METHODS

       As there are no additional values in the control only the methods in Net::LDAP::Control are available for "Net::LDAP::Control::Relax"
       objects.
