Weird unicode issue in Container#logs() output

[kfatehi]

Hi, first of all thanks for this module! Second, I have a strange issue / question but I'm not sure if it's a Docker thing or a dockerode thing. Please see moby/moby#7375

Thanks!
It's normal in ansi terminal output :)

Had to solve that same problem in nodechecker.com stdout and stderr outputs.

Check this out:

https://github.com/drudru/ansi_up (great lib to convert ansi to formatted html, if you need it)

EDIT:
Just read details...
Humm that seems an encoding issue somewhere. Not the usual ansi formatting issue.
Can't remember if I ever encountered something like that.

Thank you -- I ended up doing a regex whitelist against the output -- which still sucks but at least it's readable and doesn't destroy the terminal:

var patt = /([0-9a-zA-Z'"#,\-/_ .@]+)/;
stream.on('data', function (chunk) {
  var str = chunk.toString('utf-8');
  var match = str.match(patt);
  if (match) {
    console.log(match[0])
  }
});

Will close this for now.
If we find it's source and if it's related with dockerode then it will be tackled :)

@apocas please see moby/moby#7375 (comment) should this be handled by dockerode, or my downstream application ?

[apocas]

Humm. Dockerode already tackles this and "demuxes" the streams for you if you want.
Now i think you probably are just not attaching correctly or forgot to demux the stream.

Check this attach scenario in here: https://github.com/apocas/nodechecker-tester/blob/master/lib/container.js#L120

Are you attaching and demuxing like this?

[kfatehi]

Ah so I need to use that -- sweet deal thanks @apocas

[apocas]

No problem. Sorry for not figuring out what was happening faster, I thought you were already demuxing :)

[kfatehi]

All good man thanks for building this BADASS library :)

Is there any suggested solution for this? The solution by @kfatehi works but it still shows some weird chars
