listgroupsandmembers.py fails when user name has non ascii characters

[iyepes]

When a user name has non ascii characters and script is used like:
python listgroupsandmembers.py > user-report.csv

It fails with the following message:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xf1' in position 86: ordinal not in range(128)

Probably not an elegant solution, but we fixed it adding ascii replace, so non ascii characters are replaced by "?" sign

membername=member['name']
membername=membername.encode('ascii', 'replace')

The reported issue does not appear when python listgroupsandmembers.py shows results on console.
