Describe the bug

Receive Error: E020: Could not parse server response. Is the bookmarks app installed on your server? JSON.parse: unexpected character at line 1 column 1 of the JSON data

It might be a result of charset issues, I have a lot of bookmarks, but I already ran the emoji troubleshooting.
The strange characters I have besides emojis (which are displaying fine in my nextcloud folder) are: · ® and •

I'm pretty sure this is linked to #992 ?

It seems like the bookmarks still upload? But I'm not sure b/c I'm also using the Android app and they may have uploaded from there...

To Reproduce

Sync ( 1000 bookmarks, maybe some odd characters exist )

Expected behavior

No error

Screenshots

The Nextcloud log entries you mentioned in #1051 show server errors, did those subside and can be ruled out as a cause of this? It's quite likely that a server error causes this error message in floccus.

Yeah, I get this error server-side when I sync: (But only when I sync using the floccus plugin on firefox, I get no errors when syncing using either the floccus android app, the nextcloud android bookmarks app, or the floccus extension on chromium)
