NAME

6       nova - OpenStack Nova command line client
7
8       The  nova  client  is  the command-line interface (CLI) for the Compute
9       service (nova) API and its extensions.
10
11       For help on a specific nova command, enter:
12
13          $ nova help COMMAND
14
15       NOTE:
16          Over time, command line functionality will be phased out of the nova
17          CLI  and  into  the  openstack CLI. Using the openstack client where
18          possible is preferred but there is not full parity yet  for  all  of
19          the  nova commands.  For information on using the openstack CLI, see
20          OpenStackClient.

946       Locale encoding issues
947
948       If you encounter an error such as:
949
950          UnicodeEncodeError: 'ascii' codec can't encode characters in position
951
952       The  solution  to these problems is different depending on which locale
953       your computer is running in.
954
955       For instance, if you have a German Linux machine, you can fix the prob‐
956       lem by exporting the locale to de_DE.utf-8:
957
958          export LC_ALL=de_DE.utf-8
959          export LANG=de_DE.utf-8
960
961       If  you  are on a US machine, en_US.utf-8 is the encoding of choice. On
962       some newer Linux systems, you could also try C.UTF-8 as the locale:
963
964          export LC_ALL=C.UTF-8
965          export LANG=C.UTF-8
