Public bug reported:

For example, a line of

  option unknown-245 "dH\"l";

in dhclient.eth0.leases should yield an IP address of 100.72.34.108 but
instead causes an exception:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/cloudinit/sources/DataSourceAzure.py", line 249, in get_data
    fabric_data = metadata_func()

    shim = WALinuxAgentShim()
  File "/usr/lib/python3/dist-packages/cloudinit/sources/helpers/azure.py", line 210, in __init__
