# This script generates the emoji.plugin.zsh emoji definitions from the Unicode
|
|
# character data for the emoji characters.

|
|
# The data file can be found at https://unicode.org/Public/emoji/latest/emoji-data.txt
|
|
# as referenced in Unicode TR51 (https://www.unicode.org/reports/tr51/index.html).
|
|

# This is known to work with the data file from version 1.0. It may not work with later
|
|
# versions if the format changes. In particular, this reads line comments to get the
|
|
# emoji character name and unicode version.
|
|
#
|
|
# Country names have punctuation and other non-letter characters removed from their name,
|
|
# to avoid possible complications with having to escape the strings when using them as
|
|
# array subscripts. The definition file seems to use some combining characters like accents
|
|
# that get stripped during this process.
