Categorise each row by the emoji categories it contains

emoji_categorize() keeps the rows of data that contain emoji and adds a .emoji_category column listing the distinct Unicode categories present in that row (for example "Smileys & Emotion"), separated by | when a row spans more than one category.

Usage

emoji_categorize(data, text)

Arguments

                          "flag \U0001f3c1\U0001f600",
                          "nothing"))
