--- Comment #2 from Myles C. Maxfield <mmaxfield at apple.com> ---
When we open a webpage, we unconditionally translate the page from whatever character encoding the page is in to Unicode. GBK is an encoding used for Chinese, and includes 14 characters which do not have associated Unicode codepoints, so they are assigned codepoints in the private use area. Chinese fonts have glyphs for these particular codepoints. We should assume that all documents using the GBK character set should be using a chinese “lang” attribute (unless otherwise specified). That would change our fallback font to one that has these particular glyphs.
