On my super out of date mac, Allo renders an unrecognized emoji as U+25A1 WHITE SQUARE, not U+FFFD REPLACEMENT CHARACTER as it should. Anyone know if this is Mac's fault, Chrome's, or Allo's? (/cc @FakeUnicode)pic.twitter.com/DdTMjoFJ7L

"used to replace an incoming character whose value is unknown or unrepresentable in Unicode" I would think "unknown" is the right term to use here
maybe? I mean, we have a lot of codepoints whose values are known but have no assigned meaning
Maybe it depends on how the implementor reads the spec
Plain white square is still hella wrong though
