UTF-8 encoding issue

[iheos]

I found the reason why the parser is not detecting the document's encoding, it's because the tool is not returning the charset in the MIME Content Type of the part that contains the document (only in the part that contains the SOAP response).

Here's a sample response from the tool for a RetrieveDocumentSet request:

--MIMEBoundary112233445566778899
Content-Type: application/xop+xml; charset=UTF-8; type="application/soap+xml"
Content-Transfer-Encoding: binary

Is this an issue that could be fixed in a future release or am I missing something here?
