Browser fällt nach UTF-8 zurück

[Kevin]

HTTP-Live-Headers in Firefox wäre ein guter Start.

POST /login.php HTTP/1.1

Da gibt der Server also UTF-8 zurück. Aber warum? Die allererste Zeile Code ist immer
header("Content-Type: text/html; charset=iso-8859-1");
Außerdem sollte das meta-Tag ja eigentlich für Klarheit sorgen:
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">

Erneutes aufrufen derselben Seite nach dem Login bringt:

GET /login.php HTTP/1.1

Dann stimmt's...

So denn,
