Hi, I have the same problem and tracked it down to the rpl package, at least on my system. The “setup.py” of rpl claims to be encoded in UTF-8 but is not (file tells me that is ISO-8859). The problem is in the name of the author.
Removing rpl (or rebuilding it with a corrected “setup.py”) make the problem disappear on my system. Do other people affected by this bug have rpl installed and does removing it solve the problem? Cheers, Yannick
