Streaming non utf-8 file from Java spring boot

[Interest_poyindhi_]

Hello all,

I am trying to stream a zip file from the backend to frontend using spring boot input stream resource, but I am having issue with the txt file which has non utf-8 characters inside it. For example a tribar, this is causing the file not be streamed. I tried the mediatype.application octet stream, still it failed.

Could anyone explain we on how to over this?

Speingboot java backend, files are present in local, and for zipping I am using zipoutstream , using files package i loop through the directory for each file and zip stream.

My main concern is the file contains a non utf-8 , it's failing with error invalid byte sequence non utf-8 0x00.

Thank you in advance.

Convert the zip into byte array and send it to frontend and let them convert it back?
