Safari send incorrect "raw POST data" via XMLHttpRequest.
Test using URL above.
Download the attachment (php+js source) for analysis.
Note: the POST string should send as UTF-8 encoded.
Safari breaks only some utf-8 characters (all are contained in the $norm string, after uridecode).
Technically, this is the same as bug 30387.
