Emoji name, unicode and category crosswalk — emoji_unicode

A table with one row per (name, glyph) pair, not one row per name and not one row per glyph. 5761 rows cover 4698 distinct names and 4853 distinct glyphs, because the mapping is many-to-many in both directions:

Usage

emoji_unicode_crosswalk

Format

A data frame with four columns:

emoji_name: The emoji name / shortcode (e.g. "grinning").
unicode: The emoji glyph.
emoji_category: The Unicode category the emoji belongs to.
key: Codepoint-normalised key (U+FE0F stripped) for robust joining.

Source

Derived from the emojis table of the emoji package; rebuilt by data-raw/crosswalks.R.

Details

a glyph appears once for every GitHub-style name it is known by (the grinning face is both "grinning" and "grinning_face"), and
a name appears once for every spelling of the emoji it names – 973 do, because the qualified and unqualified forms of an emoji are separate rows that share one alias (A_button_blood_type_ names both U+1F170 U+FE0F and the bare U+1F170).

So a join by emoji_name duplicates rows for those 973 names. Join on key – which collapses the spellings – or dplyr::distinct() the columns you need first.
