Yowsup: Encoding Error

Created on 14 Jun 2016  ·  10Comments  ·  Source: tgalal/yowsup

Trying to reistablish connection with WhatsApp contacts now that whatsapp-purple is abandoned, I tried yowsup once more. Unfortunately, it crashes shortly after logon. Sometimes, a few messages are actually received prior to the UnicodeEncodeError. Revision is todays pip version installed by pip install yowsup2 --upgrade.

$ yowsup-cli demos -l REDACTED -y

@hoehermann
I have a solution for you.

change line 511 of yowsup/demos/cli/layer.py file by:

MESSAGE = messageOut.encode('latin-1').decode() if sys.version_info >= (3, 0) else messageOut.encode('utf-8'),

if you want to see the nicknames or aliases in the "cli". add here the nickname and change this line by:

FROM = self.jidToAlias(sender),

this seems to happen for voice messages. It tries to decode it as ascii I think

I doubt it's just for voice messages. Here is another one:

As you can see, messages are received. But things fall apart as soon someone sends me a message containing a German umlaut (ä in this example). I assume, the error occurrs when writing messages to the terminal. Python might try to encode with ASCII although my terminal uses UTF-8.

@hoehermann are you sure if encrypted media in groups is supported by master code?

jlguardi picture jlguardi on 25 Jun 2016

@jlguardi No, I am unaware aof the support of encrypted media in group chats. As you state in https://github.com/jlguardi/yowsup/issues/87#issuecomment-224777859 , there is none.
By looking at the trace, I cannot relate this problem to encrypted media in a group chat. If this is the case, I still would like yowsup to ignore the message and print a warning rather than crashing alltogether. Problem persists in f510d44 .

I am currently investigating this issue. For future reference, receiving an image in an encrypted group chat triggers an exception being handled and printed as

I am now on f510d44 using python 2.7. I helped myself by editing yowsup/demos/cli/layer.py, surrounding the flaky call to self.__class__.MESSAGE_FORMAT.format with a try-except block. A less than ideal solution, but at least I can follow conversations now. Exceptions occur when receiving emoji in messeges like

I have a solution for you.

change line 511 of yowsup/demos/cli/layer.py file by:

MESSAGE = messageOut.encode('latin-1').decode() if sys.version_info >= (3, 0) else messageOut.encode('utf-8'),

if you want to see the nicknames or aliases in the "cli". add here the nickname and change this line by:

FROM = self.jidToAlias(sender),

I did not try the jidToAlias hint, but your proposal for layer.py is looking very good. I want to test it some more, but it looks stable.

god bless your soul! adding the .encode worked for me. been struggling the whole afternoon

MESSAGE = messageOut.encode('latin-1').decode() if sys.version_info >= (3, 0) else messageOut.encode('utf-8')

For me it worked changing line 511 as follows:
MESSAGE = messageOut.encode('utf-8').decode() if sys.version_info >= (3, 0) else messageOut
But it still crash when receiving files (image, video, PDF, etc)
I'm using Python version 3.6
