[PATCH 1/2] modem-helpers: if operator not in UCS2, see if already valid UTF-8

[Colin Helliwell]

Might have hung this off the wrong thread, but it's along the same lines.
I've just noticed that whilst the mmcli status now decodes the operator, the --sim status doesn't:

# mmcli -m 0
...
  3GPP     |           imei: '358606050452806'
           |  enabled locks: 'none'
           |    operator id: '23415'
           |  operator name: 'vodafone UK'
           |   subscription: 'unknown'
           |   registration: 'home'
  -------------------------
...

# mmcli -m 0 --sim=0
SIM '/org/freedesktop/ModemManager1/SIM/0'

             |   operator id : '23415'
