To be honest, I dont know where does it come from

Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7

My page is fully UTF-8

My clients are normal browser right now, how can i make them to declare the content-type for each part?

I do not know. If the Content-Type is absent then it means a content type of "text/plain". But under those conditions (unless out of band information is utilized) one has to assume the content is encoded in UTF-8.
The only clue that ISO-8859-1 is utilized is the following in the logged output of the POST request:
 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7

Paul.

Thanks,
