703548 - ajax request: utf-8 is added despite charset being set

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Werner Punz]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

I created a page which uses iso-8859-15 as encoding and I am sending an ajax request:
with following content type:  application/x-www-form-...ed; charset:ISO-8859-15



Actual results:


Now the follwing happens upon issuing the request following content type is issued
application/x-www-form-...ed; charset:utf-8; charset:ISO-8859-15

So Firefox appens utf-8 ignoring both the page content type and the content type passed down already, which results in a bogus request and/or wrong encoding.



Expected results:

The content type passed down should look like the initial one, every other browser does not have this issue.

Ok correction, I found a small bug in my code. Now the encoding is passed down properly. And I get another bug:
When I pass down application/x-www-form-...ed; charset=ISO-8859-15
Firebug shows me that UTF-8 is passed down as request header application/x-www-form-...ed; charset=UTF-8

All other browsers correctly pass down the original request header.

Ok I did a server side test. Firefox indeed enforces a content-type of UTF-8 no matter what content type is passed down on the client. The charset passed down by the client simply is ignored. This is indeed a bug.

Unfortunately, this never got progressed, and the reporter is now inactive. Marking as incomplete, if this is still an issue, I'm sure someone would raise it.
