.torrent encoding ("Unknown encoding")

[NicolaiS]

If a torrent file have the "8:encoding" tag, but doesn't specify how the file is encoded ("0:"), then deluge gives an "Invalid File - Unknown encoding: " error.

Torrent files shouldn't be looking like this:

13:creation date
 i1292357935e

8:encoding
 '''0:'''

4:info
 ...

( they should be looking like this: )

13:creation date
 i1347442918e

8:encoding
 '''5:UTF-8'''

4:info
 ...

But lately I've seen a few with "8:encoding0:" I know how to manually fix this, but most end-users don't, so a default encoding of UTF-8 (in case of the encoding == "") would be preferred.

More info: Deluge doesn't give this error, if the "8:encoding" isn't there.

Tested on: Deluge 1.3.5 (libtorrent 0.15.10.0)

Here is proposed fix for deluge/ui/common.py:
