Possible reason for exclusion of 8s in A111065

[Alonso Del Arte]

For the recently added A111065, numbers that look the same when
printed upside down, a note says that for some reason 8s have been
excluded.

The reason could be that 8s in most fonts have a slightly bigger
bottom circle. To some people, this might be a large enough difference
to realize the number is upside down. Sequences of this sort are very
dependent on not just a specific character set (the Wikipedia article
on strobogrammatic numbers notes that these numbers would not be
strobogrammatic in the Gurmukhi script of India) but on a specific
font. Thus, 1s have probably been also excluded from A111065 because
1s on most Roman script fonts have top serifs.
