This looks like a behavior change, not just like a replacement?

Sorry, I forgot to call that out. The function does nothing:

_WKGetVerticalGlyphsForCharacters:
00000069        pushl   %ebp
0000006a        movl    %esp, %ebp
0000006c        xorl    %eax, %eax
0000006e        leave
0000006f        ret

-               : CTFontGetGlyphsForCharacters(fontData->platformData().ctFont(), buffer, glyphs.data(), bufferLength))) {
-        // When buffer consists of surrogate pairs, WKGetVerticalGlyphsForCharacters and CTFontGetGlyphsForCharacters
-        // place the glyphs at indices corresponding to the first character of each pair.
+    } else if (!fontData->platformData().isCompositeFontReference() && fontData->platformData().widthVariant() != RegularWidth

         unsigned glyphStep = bufferLength / length;
         for (unsigned i = 0; i < length; ++i) {
             if (!glyphs[i * glyphStep])
