error form

I have dis problem wiht data assist when i want to insert into data base...

Warning: A form was submitted in the windows-1252 encoding which cannot encode all Unicode characters, so user input may get corrupted. To avoid this problem, the page should be changed so that the form is submitted in the UTF-8 encoding either by changing the encoding of the page itself to UTF-8 or by specifying accept-charset=utf-8 on the form

sounds like the server has the default character set in the php.ini file set to windows-1252, you can try over riding that by adding the following code at line 1L

<?php ini_set('default_charset', 'UTF-8'); ?>

or you may need to try setting the header for the page:

<?php header('Content-Type:text/html; charset=UTF-8'); ?>

if those 2 fail, you will nee to contact the host to have them change the servers default character set to allow UTF-8 form data to be posted.
