Description Andre-John Mas 2007-01-30 11:19:22 PST
When I visit http://www.wikipedia.org/ I notice that some fonts aren't being rendered correctly. I would expect them to be rendered correctly. I have confirmed this with nightly r19247, on MacOS X 10.4.8

A quick discussion with a friend suggests that this may be due to no suitable font being found. The most complete font around is apparently 'Arial Unicode MS', which comes with MS-Windows. Copying that over from a Windows system seems to have reduced the number of misrendered characters.

The resolution to this issue might be for Apple to provide a suitably complete font with MacOS X, in the same manner as Arial Unicode MS.

Most problems visible at this page are indeed caused by missing fonts, and certainly do not indicate WebKit bugs.

However, Gothic characters are rendered as empty boxes (instead of Last Resort characters), and this is wrong. Re-titling the bug to reflect this, as this might turn out to be a WebKit issue.

Is it? Anyway, the difference is due to the different code paths being used. On Tiger, the simple code path uses the "missing glyph" glyph from the primary font, and the complex code path uses the last resort font.
