[Bug] "Error when syncing media data java.io.IOException" when syncing media files with "🔊" emojis in the file name?

[sudomain]

EDIT: I emailed the deck author, "The AnKing", and they've agreed to remove the Unicode character from the names of the affected media files for this deck. It's no longer an issue for this specific deck, though the problem may arise for other decks.

Reproduction Steps

1. On desktop Anki, download and import AnKing Step 1 V9 Step 2 V4 with Media.apkg from Google drive. Which I found from this reddit comment

2. After import completes, initiate sync from desktop to ankiweb

3. After sync completes, initiate sync from ankiweb to AnkiDroid

4. During the sync process, there will be an error similar to this:
   

5. Decide you can live without that .jpg file, so open your file manager on desktop, delete the problem file, check media, and sync again.

6. This time when pulling from ankiweb, you'll get the same error about a different file:
   

7. Since these are different .jpg files, the byte sequence error must be triggered by something in common with both files. Take a guess that it's the "🔊" in the file name

8. On desktop, open your file manager and find all files in collection.media containing "🔊". Delete them, check media, sync from desktop to ankiweb.

9. On the sync from ankiweb to AnkiDroid, there will no longer be an issue.

Expected Result

I'm not sure if there's anything AD can really do. I thought I'd document this error because I couldn't find anything about strange unicode code point such as 🔊(U+1F50A) in file names. I didn't make the deck, but afaict there's no real need for it to contain such emojis in the name of .jpg files. I'm hoping to point the deck maintainers to this issue and request they change the file names.

Actual Result

See screenshots above.

I'd suggest leaving the issue open, then. Even if it's not supposed to work, we should at least add an understandable error message.

I found #5192 on a related search, and just thought I'd connect the two issues because they seem related. fwiw, one of the fixes introduced in desktop 2.1.45 includes:

"Strip invalid unicode from filenames in media check"

Hopefully this means the unicode causing this issue, and hopefully desktop will expand to:

1. when the user adds media in the note editor
2. when the user syncs (thus preventing the issue on ankidroid)

If it happens after an 2.17 alpha is put out, please let us know.
