28 # Zero-width emoji modifiers and components
29 # NOTE: Some of these characters would normally be single-width according to
30 # East Asian Width properties, but we deliberately override them to be
31 # zero-width because they function as modifiers in emoji sequences.

54 # Double-width emoji ranges
56 # Many emoji characters are classified as single-width according to Unicode
57 # Standard Annex #11 East Asian Width property (N or Neutral), but we
58 # deliberately override them to be double-width. References:
64 #    universally render emoji as double-width characters regardless of their
67 #    Emoji width (https://www.w3.org/TR/jlreq/)
