> But the most jarring issue for me is that it mangled all non-ascii filenames. They are stored as UTF-8 in the DB, but the client saves them as Windows-1252 or something. So I ended up with hundreds of gigabytes of files with names like фикац, and I can't just re-encode these names back, because some characters were dropped during the process.

Filenames are probably the most valuable of metadata for them to mangle. I value them as much as I do file creation/modification times. A backup program is dead to me if they mess up either of these.

I think it should be trivial for you to pipe your request into Claude now, and get them to write a quick script. Hope that'll free you from Backblaze for good!
