Hi Oleg,
Appreciate the prompt response.
Do you know what the correct method is of sending filenames containing
non-ascii chars?
From what I've read in http://www.faqs.org/rfcs/rfc1867.html:
"if the file name of the client's operating system is not in
US-ASCII, the file name might be approximated or encoded using the
method of RFC 1522"
Which to me equates to encoding the filename using
javax.mail.internet.MimeUtility.encodeText(). The software I'm uploading
to however doesn't decode the filename. Neither do other upload servlets
such as http://www.servlets.com/cos/ and
http://commons.apache.org/fileupload/index.html.
Thanks

Hi,
When making a multipart post uploading a file with a filename containing
non-ascii characters, the filename appears to be incorrect written to
the http request.
If you look at the code, sendDispositionHeader() essentially sends the
filename.getBytes( "US-ASCII" ):
http://hc.apache.org/httpclient-3.x/xref/org/apache/commons/httpclient/methods/multipart/FilePart.html
However, the browsers I've tested with will send the filename.getBytes(
"ISO-8859-1" ) version of the filename and thus the software that's I'm
working with that receives the upload is decoding the filename correctly.
Would anyone else concur that this is a bug?
Andy,
This is definitely not a bug. Non-ASCII characters are not allowed to be
present in the MIME elements such disposition headers. Common browser
applications violate the MIME spec. Plain and simple.
For those who do not give a flying damn about standards compliance,
HttpClient as of release 4.0-alpha3 provides a browser compatibility
mode for multipart coded entities.
Hope this helps
Oleg
Thanks
