  # Get an Enumerable of formal name aliases of the given character. Returns an
  # empty Enumerable if the character doesn't have an alias.

  # The aliases are instances of UnicodeUtils::NameAlias, the order of the
  # aliases in the returned Enumerable is preserved from NameAliases.txt in the
  # Unicode Character Database.

  # Example:
  #
  #   require "unicode_utils/name_aliases"
  #   UnicodeUtils.name_aliases("\n").map(&:name) # => ["LINE FEED", "NEW LINE", "END OF LINE", "LF", "NL", "EOL"]
