The spec lists GraphemeBreakProperty.txt[1] and WordBreakProperty.txt[2] as the normative source for grapheme and word categorization respectively.
However, the spec also gives non-normative definitions of these properties. In particular, it defines Glue_After_Zwj[3] as > Emoji characters that do not break from a previous ZWJ in a defined emoji zwj > sequence, and are not listed as Emoji_Modifier_Base=Yes in emoji-data.txt. > See [UTR51]. Going through emoji-zwj-sequences.txt[4], there are a lot of emoji characters that satisfy this property. The kiss/heart emojis are like this, as well as every object emoji in the "Gendered Role, with object" section. However, we only count the kiss, heart, and speech bubble emoji as GAZ in the property table. The property table should include all role and gender modifiers as GAZ. Could this be updated?
