We should show non ASCII in MacOS X window title. In the past, there are no API
to do that, but in the MacOS X , there seems have one. I try OmniWeb on MacOS X
and they can display that correctly on window title. We should find out how they
do that.

Hum... Here is some research result. Not 100% sure how to do it yet.
OSStatus SetWindowTitleWithCFString (
    WindowRef inWindow, 
    CFStringRef inString
And this api will take a CFStrineRef 

And from
it seems CFString is holding unicode.

we probably should create the CFStringRef from Unicode by calling
CFStringCreateWithCharacters (see

The code which may want to change is in widget/src/mac/nsMacWindow.cpp

1169 NS_IMETHODIMP nsMacWindow::SetTitle(const nsString& aTitle)
1170 {
1171 Str255 title;
1172 // unicode to file system charset
1173 nsMacControl::StringToStr255(aTitle, title);
1174 ::SetWTitle(mWindowPtr, title);
1175 return NS_OK;
1176 }

My patch work nicely on MacOS X without problem. When I run in MacOS 9 with the
carbon build, it will crash the second time it set a non ASCII title to the
title bar. 

if you can provide a stacktrace of where it crashes, we can file a bug with 
apple. i'd prefer not to check in anything we know crashes on carbon os9 since 
even though we don't really support it, it might hork up embedding clients who 
want to use it.

I have no way to produce a stack for the crash on MacOS 9 with the early patch. 
It simply stop running and exist the running section without drop into debugger. 
The new patch work better since it only go to the new api if it is running on 
MacOSX or later.
