Status: RESOLVED DUPLICATE of bug 150131

(Core :: Internationalization, defect)

Description

[Marc Mongenet]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.0) Gecko/20020529
BuildID:    2002052918

Non ASCII (ISO-8859-1) characters are displayed as '?' in the window title. This
happens with local pages as well as remote (HTTP) pages.

My system is an up to date stable Debian 2.2. I use fvwm 2 as window manager.
This bug was not present with old (like 0.9.5) versions of Mozilla. This bug is
also not present on Windows 2000.

Reproducible: Always
Steps to Reproduce:
1. Load URL
2. Look at the window title

Confirm:  this is an old problem, bug 9449 used for all platforms, but now bug
9449 is for windows only.

Let's keep this one for linux only.

Problem solved for ISO-8859-1 characters!

User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.0) Gecko/20020529
BuildID:    2002052918
OS:         GNU/Linux Debian 2.2 (up to date)

I solved the problem by setting LC_CTYPE=fr_CH (french-speaking part of
Switzerland, we use ISO-8859-1) before running Mozilla. 
BTW it also solves the problem for the 'less' application. Interestingly,
'more', 'cat' and Navigator 4 always work well with accents.
LC_CTYPE does not need to be a global setting, I can 'export LC_CTYPE=fr_CH'
juste before 'mozilla&', so it is probably not related with the Window manager
(fvwm 2.2.4) or X (XFree86 3.3.6).

So, is it a Mozilla (and 'less') bug? I don't know, Unix locale is one of the
nearest thing to black magic I know of. But a release note could be at least
welcome.

I never played with locale before. Here is the configuration I used until now,
given by the 'locale' program:
LANG=POSIX
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_ALL=

And here is my new configuration, correcting this bug on Mozilla:
LANG=POSIX
LC_CTYPE=fr_CH
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_ALL=

Note that this setting also solves
http://bugzilla.mozilla.org/show_bug.cgi?id=104027
for me!

But when visiting a page with non ISO-8859-1 characters in the title
like http://www.hani.co.kr/ or http://www.haaretz.co.il/, '?' still
appears in the window title instead of non-ASCII characters. Everything
else (including tab titles) is OK so it is maybe not a Mozilla problem?

accepting; but I think I need platform developer help.

Very few window manager can accept utf8 string now. In most situations, we have
to pass string in native encoding. In order to make it work, the local must be
set correctly. In another word, the title bar can only display japanese
character under japanese locale.

See 
http://www.mozilla.org/releases/mozilla1.5/known-issues-int.html#display

(and bug 150131)

If you want to get  any Unicode characters rendered in the title bar

  1.  use the properly I18Nized Window Manager (fvwm was not the last time I
checked. There's nothing Mozilla can do for such a WM)

  2. use a UTF-8 locale (whatever your language is) That is, ja_JP.UTF-8,
en_US.UTF-8, ru_RU.UTF-8 etc. 

  3. configure your WM  to use a font with the most comprehensive character
repertoire (if it can only use one font at a time)
