Seems that the repr_locals does not handles nicely when cannot convert locals to ascii. Should we here ignore errors and maybe prin a warning instead?

[RonnyPfannschmidt]

on python2 any repr must be bytes, as per https://docs.python.org/2/reference/datamodel.html#object.__repr__

[gaborbernat]

You're right, can/should we maybe just give a better error message? 🤔

[RonnyPfannschmidt]

its not clear to me where and how to correctly handle this

[asottile]

I think this is a duplicate though I'm having trouble finding it -- also thought we fixed this too 😆

is it this one? #1693

[asottile]

hello, first off thank you for the issue!

python 2.x support has ended for pytest core.

we've decided in #7296 to close the python-2-specific issues to free up some space in our backlog. however, in accordance to our python 2.7 and 3.4 support community patches will still be accepted to the 4.6 series to fix bugs for python 2. (so if this issue is important to you and you have a patch to fix it, feel free to make a PR targeting the 4.6.x branch despite this ticket being closed).
