168498 - CJK Character Corruption Under UTF-8

Status: RESOLVED EXPIRED

(Core :: Internationalization, defect)

Description

[Kazuhiro Suzuki]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1) Gecko/20020826
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1) Gecko/20020826

After Mozilla crashes several times, CJK characters become corrupt whenever
encoded in UTF-8.  For example, bookmarks, the titlebar, Google.com (under
Japanese preferences), and the exported bookmark file when read in the browser.
 CJK characters continue to appear, but the characters are different.  Once the
corruption occurs, I have been unable to undo it.

The problem occured again after a fresh reinstall of Windows XP.

Reproducible: Always

Steps to Reproduce:
1.  Install Windows XP
2.  Install Mozilla 1.1
3.  Bookmark websites where the title incorporates CJK characters, and write the
title down.
4.  Crash it a few times.
5.  Compare the CJK characters in the bookmarks from what it was before.
Actual Results:  
The CJK character in the bookmarks did not match what it displayed before.

Expected Results:  
It should have continued to display the same characters.

The crashes may have been due to lack of memory after loading several
applications with only 256 MB of RAM

It may be difficult, but try getting screenshots from a recent build showing
what is going on.

I've just tested this with a 1.7 branch build on windows XP and after logging
into my hushmail account and making several hushmail transactions (composing a
couple of mails, and reading a couple of mails) my memory usage trippled from
atartup at around 20MB to 58MB using hushmail. It didn't drop, according to
windows task manager, when I left hushmail and visited mozilla.org -- until I
minimized and restored the window, at which point it returned to about 21MB.

But this seems to happen with any Java site I visit. Take
http://java.sun.com/applets/other/Bubbles/index.html for example. If I start the
browser it's at about 20MB. I visit the Java bubbles demo and it jumps up to
just over 40MB. I leave the demo and go to mozilla.org and it stays at 40MB.
Minimize and restore the window and it returns to just under 20 MB. 

this sounds a lot like bug 123191 to me.

Asa, this bug isn't about hushmail and isn't about memory usage....
