Status: VERIFIED DUPLICATE of bug 182650

(Core :: Internationalization, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021226 Debian/1.2.1-9

If you select View->Character coding->Western (ISO-8859-15), the first post from
the example renders with invisible text lines. You can see them selecting
fragments with the mouse cursor. If you choose ISO-8859-1, everything is OK. It
seems that this post contains some Windows-1252 encoding specific characters,
like apostrophe (0x92).

I can't reproduce this bug: I just see the apostrophes as ? 
Can you test with a nightly build from www.mozilla.org?

Side note: we are inconsistent in our treatment of Windows-1252 characters in
ISO-8859-{n} encodings, this is discussed a bit in bug 185590.

Tested with a nightly build and releases 1.2.1 and 1.1. All of them show some
character (depending on the font) instead of the apostrophe, so no "disappearing
text" happens.
Tested again with the 1.2.1 build which revealed the bug, and text disappears
again. Think I've found the difference. The build with the strange behaviour is
an xft-enabled one. It was installed including Debian package mozilla-xft. Here
you have the description:

>Description: Mozilla Web Browser - Xft support files
> This package includes just only /usr/lib/mozilla/components/libgfx_gtk.so
> which was compiled againt libxft2 to enable xft support.

I've tried different fonts and every time the "disappearing" effect happens.
So, as far as I've been able to find out, this bug only happens in xft-enabled
builds.

If this is xft-specific, then it would be a dupe of bug 182650.
