I love to have this option as well, any plan to get merged?

Thanks for the contribution. In calibre-web there is a setting config_unicode_filename which should lead to the right filename if not set. I agrre with you that "old" files stored in the english name expression are downloaded in the "old" style.
I'd like to ask you to respect/apply this setting before converting the file name
