/**
 * Kitty Unicode-placeholder row/column diacritics.
 *
 * From the kitty graphics protocol spec (rowcolumn-diacritics.txt): combining
 * class 230 marks with no decomposition mapping. Index N encodes row/column N.
 *
 * Vendored because it is a frozen table — it is derived from Unicode 6.0.0 and
 * will never change. 297 entries, so images up to 297x297 cells.
