- Apache config
- PHP config
- PHP MySQL module config
- MySQL general config
- Each text/char/varchar field in the particular MySQL tables
- When you process the Data in your PHP Script and when you receive/transport Data via GET/POST
- In the metadata each HTML site
- On each AJAX Request you make
- On each browser visiting the site
Thats not only plain confusing for the admin but between each program/module you have the possibility to somehow screw up something with the conversion if not all of them is set to UTF-8
It's always been a pain in the ass to make my websites UTF-8; some users always had problems getting it displayer correctly.
Now i got the problem that normally submitted data works fine, but data containing umlauts submitted over AJAX are displayed wrongly. Hail utf-8 -.-
