Description

12 years ago
User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322; .NET CLR 2.0.40607)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050207

If you look at the page at 
http://weblogs.asp.net/michkap/archive/2005/02/07/368570.aspx, it had the 
string "àáâãäå" in different non-normalized forms (i.e. some characters 
composed, some decomposed).

All the strings look the same in IE on Windows, but both Mozilla and Firefox 
display the strings incorrectly (though differently, for some reason).

Reproducible: Always

Steps to Reproduce:
1. Open the url http://weblogs.asp.net/michkap/archive/2005/02/07/368570.aspx
2. Have a look under the text "static void Main()..." for the various non-
normalized form of the string "àáâãäå"
3. On Mozilla and Firefox, the string all look different, even though they're 
supposed to look the same.

Actual Results:  
Different forms of the string "àáâãäå" look different.

Expected Results:  
Different forms of the string "àáâãäå" should look the same.

This is how the text looks in Mozilla

This is how the text looks in Mozilla.	Notice how all the decomposed combining
characters display separate to the base character.

This is how the text looks in Firefox.	Notice how it seems to do a "better"
job than Mozilla - it composes some characters properly, but others are not
composed, and still others have no or the wrong accent!

Notice how all the strings look the same.  This is how it *should* be.

To display the strings in my original post, you'll have to change the encoding 
of this page to UTF-8 - I'm not sure why Bugzilla is returning ISO-8859-1... :-

By the way, which version of Mozilla are you using, and on what Windows version?
I don't see any difference between Mozilla trunk and Firefox 1.0, both on
Windows XP.

I used the nightly build of Mozilla, from a couple of days ago.  But just the 
latest release of Firefox (i.e. not a nightly build).  On Windows XP SP2.

I didn't try a nightly build of Firefox, so I don't mind if we assume that's 
the "real" problem...

This bug does not appear to be Windows specific as I am seeing the same thing with  decomposed (NFD) Unicode strings with the above text attachment on Mac OS 10.4.10 with Firefox 2.0.0.7.

In current trunk I no longer see the bug on either Windows or Mac, and for Linux it is covered by bug 197649, so I am marking this WORKSFORME.
