31293	MultiPartParser support double quotes	007	007	"Although the rfc2231 document does not indicate that values can be wrapped in double quotes. However, some third-party tools wrap the value in double quotation marks when wrapping HTTP requests (such as the filename of the file uploaded by PostmanCanary). This results in double quotes for the filename at the end of Django parsing.

Postman request body:
{{{
----------------------------677822685948106391633425
Content-Disposition: form-data; name=""file""; filename=""测试.txt""; filename*=""UTF-8''%E6%B5%8B%E8%AF%95.txt""
Content-Type: text/plain

test
----------------------------677822685948106391633425--
}}}

django got filename is `测试.txt""` not `测试.txt`

This is not a bug of Django. But I suggest Django do some compatibility processing.

CPython is also compatible with this situation.
