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
