This could be a more complex question for emoji than for writing
systems. Users might have different expectations of what constitutes
"support" for emoji as compared to, say, Latin or Kanji. They might
expect to be able to select text or emoji rendering via U+FE0E and
U+FE0F, or might expect support for ZWNJ sequences. fontconfig may or
may not be wired to take this into account.
On the other hand, as far as full or less-than-full coverage is
concerned, does fontconfig currently insist on 100% coverage of all
characters in a script? Nearly all fonts offer Basic Latin (ASCII)
support, while relatively few have glyphs for the Latin Extended-E
block. Is the latter required in order to claim "Latin script support,"
and if not, would similar criteria apply when determining "emoji
Not trying to be critical, just trying to understand the expectations.
