45 * Remapping tables are used to map Unicode points to glyphs. They need
46 * to be sorted, because vtfont_lookup() performs a binary search. Each
47 * font has two remapping tables, for normal and bold. When a character
48 * is not present in bold, it uses a normal glyph. When no glyph is
49 * available, it uses glyph 0, which is normally equal to U+FFFD.
