Comment (by madmax):

We are getting it in the string but with the plane nixed: the UTF8 for
 0xf30d instead of the one for 0x1f30d.

 This one looks like a confusion between codepoints and glyph indexes.
 Glyph is unsigned short, I guess it's more for a glyph index inside a font
 and not a codepoint. In that case code like
 
[https://github.com/haiku/webkit/blob/90d5fec996134cc8bda5e73ce770ec0a13d2197b/Source/WebCore/platform/graphics/haiku/GlyphPageTreeNodeHaiku.cpp#L61
 this] or

 this] would be wrong. Maybe widening Glyph and considering it equal to a
 codepoint would solve that or is it too bold a hack and would need the
 review of lots of webkit core code? (That is, if we don't have something
 in BFont or wherever that would give the required data)
