WebUI Json dumps Error

[yueyoum]

when upload torrent via the web ui which the torrent's content contains CJK (Chinese, Japanese, Korea) and not encoding by UTF8,

An Error will occurred at ​https://github.com/deluge-torrent/deluge/blob/develop/deluge/ui/web/json_api.py#L213

The error message is:

[ERROR   ] 11:59:38 json_api:271 'utf8' codec can't decode byte 0xe5 in position 0: invalid continuation byte
Traceback (most recent call last):

UnicodeDecodeError: 'utf8' codec can't decode byte 0xe5 in position 0: invalid continuation byte

I try to change response = json.dumps(response) to response = json.dumps(response, ensure_ascii=False), this can fix the error.

The torrent in the attach file.

I can't reproduce this. Does it give this error with the torrent you attached (with that exact name)?

However, I do get a different error when trying to add the torrent, but that is in bencode.py. Either the torrent is not 100% valid (though Transmission is able to read it), or bencode is buggy.

[bro]

The error is not due to issues with encoding of the filenames, but because the attached torrent contains an obscure field "filehash" which must be explicitly hex encoded like the sha1 and ed2k fields: ​https://github.com/deluge-torrent/deluge/blob/develop/deluge/ui/common.py#L115

[bro]

yueyoum, is the content in the torrent copyrighted?

Fixed in develop [37baf3de3c826] and 1.3-stable [5394ac5604]
