In addition to verified publishers being indicated by a check-mark, we
now have starred publishers indicated with a circled star.
If unicode support is not available, for instance with serial
connections, we use a different number of stars to represent:
* verified publishers: 2 stars
* starred publishers: 1 star
* others: no star
Because our mechanism to substitute unicode characters with ascii
equivalents expect a 1:1 mapping, we cannot simply replace the circled
start by two stars. To workaround the issue, we added a narrow
non-breakable space.
When support of unicode is available, this character shows up as a
normal space.
When support of unicode is not available, it gets replaced by a star.

In preparation for the self-refresh and snap enterprise proxy work, both
of which will require talking to the snapd API.
This also makes the "snaps-from-examples" fakery happen at a lower level.
