When choosing the plugin menu item Open console, the following appears in the IPython Console plugin:

An error ocurred while starting the kernel
The error is:

RuntimeError: An error occurred while trying to load the kernel connection file. The error was:

[Errno 2] No such file or directory: '3ad02cfe‑e528𔂮f8f‑b831�f24999926'

This is using the master branch of both plugin and Spyder.

Looking at the file name, this may be an encoding issue.
