The localeCompare table now covers U+0363-U+036F, U+00BC-U+00BE and U+2044 FRACTION SLASH, so strings containing them follow Node's collation instead of code-point order. A combining Latin letter is its letter's primary at the letter's secondary, with a tertiary weight between the letter's case forms where Node places it, and the combining class it shares with the diacritics it reorders with. A vulgar fraction is the elements of its compatibility decomposition (1, U+2044, 4), each with the tertiary weight Node places the fraction at among that position's forms, so it orders after both 1⁄4 and ¹⁄4. The generator's check adds the fractions' slash and superscript spellings and the combining letters around each diacritic. SC6003 and the limitations page describe the new coverage. The generated lookup indexes one dense table for every code point below U+0370, with the gaps between ranges marked uncovered, and checks the ranges above it (now U+2044) after that, so a Latin lookup is one comparison instead of up to four.
