This is a continuation of https://rt.perl.org/Public/Bug/Display.html?id=127047 >From http://unicode.org/reports/tr51/#Emoji_ZWJ_Sequences: “The U+200D ZERO WIDTH JOINER (ZWJ) can be used between the elements of a sequence of characters to indicate that a single glyph should be presented if available.” “So to the user, these would behave like single emoji characters, even though internally they are sequences.” It sounds like we shouldn't cut these sequences in half when doing .substr (which in turn means that these should be treated as one grapheme). There is a chart of possible combinations here http://www.unicode.org/emoji/charts/emoji-zwj-sequences.html, but I think that any sequence with U+200D ZERO WIDTH JOINER should probably result in one grapheme. As crazy as it sounds…
