Non ASCII attachments names are broken AGAIN

Dear Zoho Mail Team,

You did break non-ascii attachments names again.

They are displayed correct but when we try to download them we get broken names. The the attachment i've added to the request in Zoho Support.

Could you please verify you every change before rollout? You break Russian support every time. Our users are very angry.

Thank you.
