I don't see this problem in Japanese locale. Reporter, are you talking about the problem with window title on the dialog? The window title display depends on the locale. If mozilla is started in a non-Japanese locale, the window title will have Japanese characters displayed as question marks. Could you attach a screenshot? Thanks.
Please also attach the sent mail. I wonder if that was really sent as ISO-2022-JP.
utf-8 japanese subject
iso-2022-jp japanese subject
Hi, Ji, please see screen shots.

reporter, from your screen shots i can tell that you are on en-gb locale and what you're actually seeeing is not headers that are incorrect but window titles. This result is expected if you are not log on into japanese locale.

Linux bug, reassign to shanjian, cc to ftang.

Actually, this bug was fixed in a sense for Linux a long time ago. Mozilla does its best and the rest is up to a Window manager. Mozilla sets _NET_WM_NAME window property(UTF8_STRING) and window managers(e.g. I believe the latest version of kwin in KDE works fine) that know about this window property CAN interpret this and display multilingual subject/title in the window title bar. For details, see bug 9449 (comment 39 to comment 58) as well as attachment 41935 [details] [diff] [review]. See also bug 74753.
Jungshik, according to your comments in bug # 9449 this bug was fixed for Linux only for a special case: same locale > This bug has been RESOLVED (at least partially) for Linux/Unix/X11 by Frank's patch dated January 4, 2000 (see my comment on bug 2426) in that the window title bar can correctly display non-ISO-8859-1 strings as long as the locale under which window manager is running is the same as the locale/encoding in which the page viewed in browser(i.e. title) is encoded.> That's not the case for this bug report, mozilla is not running on ja-jp locale , under that locale the window titles are displaying correctly. So this particular bug was not fixed... going back to bug# 9449
I'm afraid you got me wrong. (I wonder why you quoted my comment 31 written much earlier which is irrelevant to this bug when I specifically wrote that comment 39 to comment 59 of bug 9449 had to be refered to) I've been following bug 9449 long enough to know how to tell one case from the other. The first case (displaying Japanese title under Japanese locale) was fixed by Frank in January 2000. The second case (displaying Japanese title under,say, Russian locale) was fixed later by lya Konstantinov's patch that has been checked into Mozilla source on 2001-07-13 (see comment 61 of bug 9449). In other words, this bug was _fixed_ for Linux REGARDLESS of whether the string to put on the window title bar is covered by the current locale or NOT. You should have read from comment 39 to comment 59(in bug 9449). Those comments are about putting _NET_WM_NAME window property.(please, see also attachment 41935 [details] [diff] [review]) This property has to be interpreted by window managers that understand it and used by them to put on any UTF-8 string this property contains REGARDLESS of whether that string is within the character repertoire of the present locale or NOT. Then, why this bug report? That's because the reporter does not use a Window manager that understands _NET_WM_NAME (UTF8_STRING) window property. Mozilla does as best as it can by doing its part (that is, setting _NET_WM_NAME property) and it's NOT Mozilla BUT Window managers that have to do the *rest* of the job , that is, interpreting _NET_WM_NAME and rendering its content properly in the title bar.

Given that many users still use window managers that don't understand _NET_WM_NAME property, I think this has to be 'release-noted'. That is, the window title bar can render a string made up of characters outside the character repertoire of the present locale ONLY IF a window manager compliant to extended WM spec (http://www.freedesktop.org/standards/wm-spec/) is used. Those window managers include kwin (KDE 2.2 or later) and blackbox (see the screenshots at http://www.debian.or.jp/~kubota/mojibake/window-managers.html )
> how did you decide en-gb? the headers should not effect it i think > $ locale > LC_MESSAGES=en_GB > my locale is set for japanese, there should be no problem, does mozilla not take > it from the enviroment variables? The cause of your problem is that Mozilla uses LC_MESSAGES insted of LC_CTYPE to determine the character repertoire of the present locale. I argued to Erik that LC_MESSAGES MUST be DISREGARDED when determining the character repertoire, but I failed to persuade him. It was perhaps two or three years ago. Just like you set LC_MESSAGES to en_GB with LC_CTYPE to ja_JP(.eucJP), I usually set LC_MESSAGES to C/POSIX/en_US with LC_CTYPE set to ko_KR.eucKR (well, these days, I now use en_US.UTF-8 for LC_MESSAGES and ko_KR.UTF-8 for the rest of LC_*). This leads Mozilla not to be able to render Korean string in the window title bar even though LC_CTYPE is set to ko_KR.eucKR UNLESS I use a window manager compliant to extended WM spec mentioned in my previous comment. Therefore, I was forced to write a shell wrapper to invoke Mozilla in which I reset LC_MESSAGES to ko_KR.eucKR to work around this problem in Mozilla. To see it yourself, try Mozilla with LC_MESSAGES set to ja_JP (or LC_ALL set to ja_JP). Now, I'll try once more to make my case that LC_MESSAGES should NOT be refered to when determining the character repertoire of the present locale. LC_CTYPE MUST be used instead. More specifically, 1. LC_ALL should be used if set. 2. LC_CTYPE should be used if set. 3. LANG should be used if set.
Hi Jshin, I think your idea is the best way forward, i can not think of a reason why this should not be the way mozilla works. It would solve more problems if it is as such IMO. JG
> Now, I'll try once more to make my case that > LC_MESSAGES should NOT be refered to when > determining the character repertoire of the > present locale. LC_CTYPE MUST be used instead. I filed a separate bug for this. It's bug 151112. > More specifically, > 1. LC_ALL should be used if set. > 2. LC_CTYPE should be used if set. > 3. LANG should be used if set. I'm taking back the above 'specifics'. It turned out that Mozilla uses 'setlocale(category,"")' of which the behavior is implementation dependent according to Posix and Single Unix spec. What I described above is what glibc does, but other C library may do it differently. Whatever it may be on a given platform, it would be consistent with what users of that platform expect. Therefore, we don't have to worry about it.
> the window title bar can render a string made up > of characters outside the character repertoire > of the present locale ONLY IF a window manager > compliant to extended WM spec > (http://www.freedesktop.org/standards/wm-spec/) > is used. Those window managers include > kwin (KDE 2.2 or later) and blackbox. I was wrong about blackbox. blackbox does not yet take care of _NET_WM_NAME properly. It's in its TODO list. There are some lines of code put in already(although #ifdef-ed out), but it's not yet fully implemented. Some clarification: Even with a window manager aware of _NET_WM_NAME property, arbitrary UTF-8 strings would not be rendered correctly if the window manager is launched under non-UTF-8 locale (e.g. ja_JP.eucJP, ko_KR.eucKR, fr_CA.iso8859-1, etc) This is akin to running MS IE(or Mozila with Roy's or my patch for bug 9449) under MS Windows 9x/ME, which is not based on Unicode but dependent on 'ANSI' code page (in the example above, it's EUC-JP, EUC-KR, or ISO8859-1 in Unix/Linux) On the other hand, if a window manager is launched under UTF-8 locale(ko_KR.UTF-8, en_GB.UTF-8, ja_JP.UTF-8, etc), which is similar to running MS IE(or Mozilla with Roy's/my patch for bug 9449) under Win 2k/XP, the locale under which Mozilla is launched does NOT matter. No matter what locale under which Mozilla is running(even C/POSIX) may be, _WM_NET_NAME-aware window managers should be able to render UTF-8 strings properly in the window title bar provided that the fontset (in the configuration of the window manager) is set correctly to cover the glyphs required of rendering a given UTF-8 string.
reassign this bug to Jungshik, he knows this well.

Accepting. I think the product field has to be changed to 'documentation' (is this right category for 'release note' issue? when I get confirmation that it is, I'll change the product field) because there's little, if any, that has to be modified in Mozilla source code. Something along the line of comment 20, however, has to be release-noted. This is a bit complicated issue because what's required for multilingual UTF-8 title to get rendered correctly is beyond the control of Mozilla (window managers and UTF-8 locales). It'll take pretty long before every user switches to UTF-8 locales. It'll also take a while for _NET_WM_NAME-aware window managers to replace non-NET_WM_NAME-aware window managers on users' desktops. Either of two conditions (that is, one or the other or both) has to be met for multilingual strings to be rendered correctly in the window title bar.

In comment #19, I wrote: > It turned out that Mozilla uses 'setlocale(category,"")' > of which the behavior is implementation dependent according > to Posix and Single Unix spec. What I described above > is what glibc does, but other C library may do it > differently. I was wrong again. About a month ago, I learned that how setlocale(category,"") works is not implementation-dependent but is explicitely specified by Single Unix Spec., which is the same as what glibc does and what I described in comment #17 which I mistakenly took back in comment #19.

It'll take pretty long > before every user switches to UTF-8 locales. Thansk to RedHat 8, it has already happened and I hope other Linux vendors will follow soon. On other Unix platforms, Solars 8/9 has offered UTF-8 locales for a while. So has AIX. It's unfortunate that RH 8 uses legacy encodings for CJK,though. For all other languages, it uses UTF-8. Even for CJK encodings, by modifying /etc/X11/gdm/locale.aliases, one can use UTF-8 locale. (there's another change to make in XLC_LOCALE directory). I've been using ko_KR.UTF-8 locale since last spring. > It'll also take a while for _NET_WM_NAME-aware window managers to replace > non-NET_WM_NAME-aware window managers on users' desktops. Kwin in KDE3 is one of NET_WM_NAME-aware WM. I believe metacity (the default WM for Gnome2 in RH8) also honors _NET_WM_NAME. Anyway, in KDE, all you have to do to display multilingual title displayed correctly in the window title bar is : - go to Kontrol Panel (KDE Control Panel) - go to 'Apperance and Usage' (I'm translating Korean menu back to English so that the original Enlgish menu name may be a little different) and choose 'fonts' - For Window title font, select one of 'Pan-Unicode fonts' such as 'CODE2000' (http://home.att.net/~jameskass) or Bitstream Cyberbit or Arial MS Unicode. You may not use the last one because of a license issue. - Of course, your fontconfig configuration file (/etc/fonts/fonts.conf or ~/ .fonts.conf) has to have a directory where you have aforementioned fonts. I'll test it with metacity in Gnome2 (Solaris9 reportedly uses metacity as well in its Gnome desktop) and get back here with the test result.
In case of metacity under RH8, it just works out of the box even under legacy CJK encodings are used in CJK locales. That is, UTF-8 locale is not required for metacity to honor _NET_WM_NAME. That's supposed to be the case, but some WMs don't work that way and UTF-8 is required for them to render the full repertoire of Unicode string.
