I agree with this approach. On the form page, tell the user that the field must non-accented alphanumeric, and an= y other characters will be stripped out. Just like the thousands of username and password fields throughout the interne= t have certain restrictions. Leave it on the user to enter the info correctly. Then just run Donovan's grep routine to= make sure it's clean. If you try to accommodate every possible character someone will throw at you, you'll su= rely miss something.
