Description Jungshik Shin 2010-03-02 14:18:52 PST 
On Windows, Chromium turns plane 2 characters (U+20000 - U+2FFFF) into 'blank' (nothing visible) at all unless a font covering Plane 2 is explicitly specified.  1st line should be more or less the same as the 2nd through 4th line. I'll upload a patch shortly.

patch with a layout test

Added fast/text/international/plane2.html along with the expected text/png. It's added to Skipped for Windows

This is a Chromium issue ( http://crbug.com/36329#c15 : the 2nd issue of comment 15 in that bug).

OK, but what does ucs4 > 0xFFFF do?

A comment would be helpful.  Obviously you're looking for a certain plane of characters, but which plane and why?

Otherwise I'm totally ready to r+ this.
