MacOS X come with many CJK fonts which have a lot of CJK charcters Reproduce proceudre 1. You need to install Language kits which are optional installation in MacOS X. Install all of them 2. bring up "Applications:TextEdit" with an empty page. 3. In mozilla, go to http://people.netscape.com/ftang/demo/ncr.cgi?r=0x5c=0x0 You will see some characters display some not. 4. copy all the text below the table in the "Propotional Font" Part in that pate and paste into TextEdit The copy and paste is good, you will see TextEdit will display some CJK characters and display the rest by using "Last Resort Fonts" while Mozilla display them by using "?" If you look carefully, you will see TextEdit display more characters than Mozilla, for example, In the first row, mozilla cannot display 5 characters, but TextEdit cannot display 4 characters. Mozilla cannot display U+5001 in the second row, mozilla cannot display 5 characters, but TextEdit cannot display 4 characters. Mozilla cannot display U+5010 Here are the character that mozilla cannot display but TextEdit can: 5001 5010 5024
I already have my TTF CMAP parsing patch (see bug 90804) in my local build while I see this. I guess the problem could be 1. the font which contains that glyps is not TrueType font (Open Type?) 2. The font is not encoded in platform =3 platforntSpecific=1 I probably need to tweak my TTF CMAP parsing code later to make this work.

Frank, is this going to make 0.9.4? Do you have reviewers?
no, move to m0.9.5
Target Milestone: mozilla0.9.4 → mozilla0.9.5
move to m97
Does this really block bug 90804 ? Can't you land the patch for 90804 and solve this remaining problem later ? I have the feeling the current state is good enough for most use, if people want exotic characters, they are used to importing the font needed, they are lots of PC TTF font your code should be able to parse around, so they won't be so much annoyed.
fixed and check in
