Description Rob Kaper 2006-07-23 16:24:01 UTC
Version:           3.5.3 (using KDE 3.5.3, compiled sources)
Compiler:          gcc version 3.4.6
OS:                Linux (i686) release 2.4.31

Might be related to #130234, not sure.

XmlHttpRequests containing UTF-8 POST data are not sent correctly. A simple testcase is available here:

http://www.robertjohnkaper.com/tmp/kio_utf8.html

Works fine in Firefox, but Konqueror messes up and loses input data.
Comment 1 Jan Mentzel 2006-07-29 16:00:46 UTC
Version:   3.5.3 (using KDE 3.5.3)
Compiler:  gcc (GCC) 3.4.5 (Gentoo 3.4.5, ssp-3.4.5-1.0, pie-8.7.9)
OS:        Linux i686 2.6.17-ck1-r2 #1 PREEMPT

Same problem here with german "Umlaute".

Seems to me as there runs something wrong when konqueror calculates the string length of the utf-8 encoded string.

Same problem occures in Safari-2.0.4 if in the request the content-type header is set to something different from "text/javascript".

SVN commit 576656 by dfaure:

Calling utf8() twice is expensive, calling length() on a QCString is expensive, so better not do either one :)
