Bench start fails on develop (UnicodeEncodeError: 'ascii' codec can't encode character u'\u2013' in position 145: ordinal not in range(128))

Hi there,
I tried the following, but get an error (listed below). Is this a known issue, or just a corner case that I have run into?

$ bench switch-to-develop
$ bench version
    erpnext 10.1.45
    frappe 10.1.43
$ bench update --patch

$bench start
