[Fedora-i18n-bugs] [Bug 952778] New: Unable to render combining accent with some characters under KDE

Bug ID: 952778
Summary: Unable to render combining accent with some characters
under KDE
Product: Fedora
Version: 18
Component: liberation-fonts
Severity: unspecified
Priority: unspecified
Assignee: psatpute(a)redhat.com
Reporter: bugs(a)wormhole.me.uk

External Bug ID: KDE Software Compilation 315642
Category: ---
In https://en.wikipedia.org/wiki/Stress_%28linguistics%29 the following strings
occur:
«земли́ (genitive of "earth, land") vs. зе́мли (plural of "earth,
land") in
Russian»
«In Russian and Ukrainian dictionaries, stress is indicated with an acute
accent (´) on a syllable's vowel (example: вимовля́ння)»
In all the native KDE/Qt applications I've tried, these combining acute accents
display as empty rectangles. The problem only occurs with Liberation and Ubuntu
fonts, and it doesn't occur with GTK-based applications such as Firefox when
run on the same KDE platform. (I haven't tested Ubuntu fonts with Fedora as
they're not installed by default.) It seems there's some combination of
problems with these fonts and with KDE or Qt.
To reproduce the problem in Konqueror, display the above Wikipedia article then
go to Settings / Configure Konqueror menu, then under Web Browsing, Appearance
entry, Fonts tab. For Sans serif font, select Liberation (note the default is
DejaVu); click OK or Apply. To reproduce while displaying bugzilla.redhat.com
(e.g., this bug report!), change Fixed font instead.
I've created a small HTML file here:
http://bugsfiles.kde.org/attachment.cgi?id=77513 which demonstrates the problem
(not confined to Cyrillic characters), and also shows a couple of characters
which display correctly. Change the Standard font in Konqueror to demonstrate
the problem.
To reproduce the problem in Konsole, download the file and cat it. Go to
Settings/Edit Current Profile, Appearance tab and click Select Font. Note it's
not necessary to click Apply or OK after selecting the font; all instances of
Konsole update their font dynamically as you select it.
I've reported the problem against KDE and Ubuntu fonts here:

While this is a problem that should be fixed, stress is by and large not
indicated in written Russian/Ukrainian. The only books where it is explicitly
stated are dictionaries and teaching materials for western students (for native
speakers it is so natural it does not need indication).
So working diacritics on Cyrillic letters has about the same priority as
working phonetic notation in Latin text.

Though i can add some of these stress marks in Liberation fonts. But root
problem is from qt.
Qt is not able to select characters from fallback fonts when selected fonts
does not have these characters.
This should be fixed in qt.

The Russian and Ukrainian and other Slavic language Wikipedias use the stress
marks in a lot of articles on the first occurrence of an entry word.

Right, they are giving the phonetics like a dictionnary

This was reported against Qt:
https://bugreports.qt-project.org/browse/QTBUG-32470, and is apparently fixed
in Qt 5.0.
If Qt 5.0 renders the characters the same way as GTK does currently, then I
guess that's good enough (though obviously having the accent to the side on the
capital letters and on ё isn't typographically ideal).

Is there any reason to keep this bug open?

Qt 4 is going to stay around for a long time to come. We still ship qt3 and a
handful applications still use it.

Even though i am bit reluctant to add new shapes to Liberation 1.07 since we do
have Liberation 2.0 which has much broader coverage than Liberation 1.07.
But as you might be knowing due to hinting compatibilities we are not packaging
liberation 2.0 into Fedora.
I am just thinking for some alternatives so that, users preferring character
coverage rather than fine hinting output will able to use liberation fonts 2.0
