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.
