UnicodeDecodeError in torrents.state

All my torrents have disappeared since the last update.

$ deluge -L debug

After the workaround below, all the torrents are back.

Client: 2.0.3 libtorrent: 1.1.12.0

[Ian Young]

I had the same issue as the OP. Same client versions, Arch Linux, Python 3.7.3. Can confirm that the included patch resolves the issue.

[Olivier]

In my case, it needed to be

state = pickle.load(_file, encoding='utf-8')

[Sheng Yang]

I can confirm the patch by @Olivier. Arch Linux, python 3.7.3, deluge 2.0.3-1.

[Phidica]

I also confirm the patch by @Olivier, preferring the 'utf-8' encoding. Upgrading from Fedora 30 deluge-1.3.15-12 to Fedora 31 deluge-2.0.3-5.

Why is python 3.7 using ascii encoding?
