UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 33484: ordinal not in range(128)

I get the error message below when running AP tests:-

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 33484: ordinal not in range(128)

This also fails with:-

Music app 389 on mako #250

Does that make it an autopilot issue?

[Victor Thompson (vthompson)]

I've seen this same error before. I'm not sure if I was able to get rid of it in my case. But what it seems to do is prevent AP from reporting what the actual failure was. As for the 13 failures, did your device still see your old library when the tests ran?

[Nicholas Skaggs (nskaggs)]

I'm concerned this traces back to the python3 and phablet-tools changes. Due to the fact the click package fails on the old image (and the image and click haven't changed ;-) ), the method of running must be suspected.

[Nicholas Skaggs (nskaggs)]

Leaving the relevant IRC snippet here :-)

<xnox> balloons: if a click declares autopilot directory in the manifest, it must be python3 compliant tests.

Basically, everything needs to be py3 compatible now, and the unicode errors are symptoms.

[Dimitri John Ledkov (xnox)]

Please tell me which combination of version of phablet-tools and music-app you are trying to test?

Note that 369 and earlier music-app erroneously declared python3 compatibility whilst it actually wasn't.
Thus 369 and earlier must be tested with phablet-tools <= 1.0+14.04.20140227.1-0ubuntu1

music-app 370+ can be tested with any phablet-tools in python2 or python3 modes.
