utf8 special characters problem by forms

"accept-charset" will not work on your button, it will not do anything but invalidate your page. Check this:
- <meta charset="utf-8">
- browser needs to be set to utf-8 (should be for all modern browsers) Google even removed this option and auto-detects.
- $config['charset'] = 'UTF-8';
- database utf8_unicode_ci
