Set content type to utf-8 using angularjs $ http

I upload a form with files, text, etc. in appobine blobstore:

$http({
    method: 'POST',
    url: the_url,
    transformRequest: formDataObject,
    data: event,
    headers: {'Content-Type': undefined}
})

The request is sent successfully with the follwing header:

Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryYeRxOO7y3qHNWd83

When I try to set the content type to "multipart/form-data;charset=UTF-8", I lose the border and get an error in the response:Bad content type. Please use multipart.

What is the correct way to add UTF-8 encoding?

According to RFC 1341:

As stated in the definition of the Content-Transfer-Encoding field, no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The multipart delimiters and header fields are always 7-bit ASCII in any case, and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.

Therefore, in this case you should use Content-Transfer-Encodinginstead Content-Type.

My decision should not change anything:

It turns out the use headers: {'Content-Type': undefined}was correct. Now everything works (and I just changed the backend).
