-----------
Special-casing the zero glyph page is unnecessary
https://bugs.webkit.org/show_bug.cgi?id=259180
rdar://112186000
Reviewed by Simon Fraser.
Each glyph page only holds 16 characters, so the 0th glyph page isn't really
special.
Almost no text will actually use it. So there's no need to special-case it. (I
bet
that this special-case wasn't actually created for performance, but just
because of
how our HashMaps treat 0 as empty...)
