Postman “Send and Download” Does Not Respect Content-Disposition Filename with Chinese Characters

I’m testing a file download API using Postman. The API returns a file with a Chinese filename, and I’ve correctly set the Content-Disposition header using UTF-8 encoding:

Content-Disposition: attachment; filename*=UTF-8''%E5%B9%B4%E5%BA%A6%E6%8A%A5%E8%A1%A8.pdf

When I test the API:

  • The file downloads correctly with the Chinese filename when accessed from Swagger UI or a browser.
  • In Postman, if I use “Send and Download,” the file is saved with a generic name (e.g., response) and not the Chinese filename from the header.

I’ve verified that:

  • The filename* parameter is correctly set using Uri.EscapeDataString.
  • The response headers in Postman include the proper Content-Disposition.

Is there a way to make Postman respect the encoded filename during download, or is this a current limitation in Postman?

Any guidance or workaround would be appreciated.
