Your biggest problem will be if you accept any kind of user input

Depending on your server configuration you'll probably have some
serious cleaning and filtering to do.
I often have to employ this line for example:
foreach (array_keys($_POST) as $key) $clean[$key] =
mb_convert_encoding($_POST[$key], "UTF-8");

Trying to make sure that you'll receive UTF-8 helps as well:
<form action="form.php" method="post" enctype="multipart/form-data"
accept-charset="utf-8">

I work almost exclusively in UTF-8 (language irrelevant), but I've never
had to do any of the above. The mb_convert_encoding() from UTF-8 to
UTF-8 doesn't seem to make much sense?

I agree. Provided you HTML is dished out with UTF-8 in the doctype
definiton etc. then all forms are automatically sent in UTF-8....


But what happens if you get data that's *not* UTF-8? Just because your html/form is set to UTF-8 doesn't mean that all your incoming data will be UTF-8.
