azure-cli: Getting 'UnicodeEncodeError' on CentOS and Python 2.7

Describe the bug Using any az acr command produces a ‘UnicodeEncodeError’. Other ‘az’ commands work without issue.

To Reproduce Either of the following examples produces the exact same error az acr list az acr login --name $ACRNAME

Traceback (most recent call last): File “/usr/lib64/python2.7/logging/init.py”, line 851, in emit msg = self.format(record) File “/usr/lib64/az/lib/python2.7/site-packages/knack/log.py”, line 78, in format msg = logging.StreamHandler.format(self, record) File “/usr/lib64/python2.7/logging/init.py”, line 724, in format return fmt.format(record) File “/usr/lib64/python2.7/logging/init.py”, line 467, in format s = self._fmt % record.dict UnicodeEncodeError: ‘ascii’ codec can’t encode character u’\xa0’ in position 215: ordinal not in range(128)

Expected behavior The expected behavior for the given examples is to list all ACR’s in the current subscription, and then log in to the given ACR. The responses to these commands should be as described in the linked documentation.
