REGRESSION(r272379): Characters with no fonts that support them are drawn as two .notdef glyphs in the fast text codepath https://bugs.webkit.org/show_bug.cgi?id=228097 <rdar://problem/80798113> Reviewed by Alan Bujtas. Source/WebCore: If a character is not in BMP, and we don't have a glyph for it, we'll end up with two 0 glyphs in a row for the two surrogates of the character. We need to make sure that, after shaping, these double-0-glyphs aren't preserved.
