           Summary: Characters mapped to PUA codepoints (from CJK codepages)
                    are not rendered
           Product: WebKit
           Version: 525+ (Nightly build)
          Platform: PC
               URL: http://www.wo99.com
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: help.improve.safari at gmail.com


Reproduction steps:
1. Go to www.wo99.com

Issue:
The password label ("密 码") is displayed with a rectangle in the
middle.

Expected:
A rectangular box should not be displayed in between the characters.

Other browsers:
IE, FF, Opera: work fine.

Reason:
looks like there  is a GB2312/GBK converter issue. Firefox's converter maps
'two bytes'  between 密 and 码 in the original document  to U+3000
but apparently the ICU converter used by Safari maps it to U+E5E5.

Nightly tested: WebKit r29785 

Attached is the screenshot and reduction.
