Usage

require "unicode/name"

# Name
Unicode::Name.of "A" # => "LATIN CAPITAL LETTER A"
Unicode::Name.of "🚡" # => "AERIAL TRAMWAY"
Unicode::Name.of "丁" # => "CJK UNIFIED IDEOGRAPH-4E01"
Unicode::Name.of "한" # => "HANGUL SYLLABLE HAN"

# Unicode 16 (2024) example
Unicode::Name.of "𜱼" # => "SQUARE SPIRAL FROM TOP LEFT"

# Aliases, by type
Unicode::Name.aliases "\t" # => {:control=>["CHARACTER TABULATION", "HORIZONTAL TABULATION"],
                                 :abbreviation=>["HT", "TAB"]}

# Corrections (via .aliases[:correction], then name)
Unicode::Name.correct "A" # => "LATIN CAPITAL LETTER A"
Unicode::Name.correct "Ƣ" # => "LATIN CAPITAL LETTER GHA"

# Codepoint labels
Unicode::Name.label("\0") # => "<control-0000>"
Unicode::Name.label("\u{D800}") # => "<surrogate-D800>"
Unicode::Name.label("\u{FFFFF}") # => "<noncharacter-FFFFF>"
Unicode::Name.label("\u{10C50}") # => "<reserved-10C50>"

# Best readable representation
Unicode::Name.readable("A") # => "LATIN CAPITAL LETTER A"
Unicode::Name.readable("\0") # => "NULL"
Unicode::Name.readable("\u{FFFFD}") # => "<private-use-FFFFD>"

See unicode-sequence_names for character names of more complex codepoint sequences. This is how you could use both libraries together to get the most relevant name of a character:

name = Unicode::SequenceName.of(char) || Unicode::Name.readable(char)

See unicode-x for more Unicode related micro libraries.

See unicode-name.js for a JavaScript implementation of this gem.
