Cross-Domain XmlHTTPRequest in chinese after firefox update

Question

My Firefox just did an update, and now all my XMLHttpRequest (that worked 10 minutes ago) answer in Chinese...

I can read this as responseText in firebug :

This is fun, but I really would like to have my real answer back.

Do you know if I can change a setting or something?

An important thing to know, is that my ajax code is a crossdomain request. Is it possible that something changed in the http header encoding ?

Thanx a lot !

Firefox now gives precedence to the UTF-16 BOM over HTTP. This is not a regression but an intentional change. Better not use a UTF-16 BOM if the bytes after it aren't UTF-16!
