Exception Value: 'utf-8' codec can't encode characters in position 70-72:

{code}
There are a couple different issues here. First, the Django server thinks the
file system encoding is 'ascii'. That can be fixed by setting the language and
locale of the Python process to en_US.UTF8 on the WSGIDaemonProcess
(https://modwsgi.readthedocs.io/en/master/configuration-directives/WSGIDaemonProcess.html?highlight=lang#wsgidaemonprocess).
The second issue is on the API server. The replica_catalog tables use a
character encoding of latin1 so they are not able to store file names or paths
with unicode characters. This can be fixed by converting these tables to 'utf8'
character set.
