+++ This bug was initially created as a clone of Bug #956192 +++

Description of problem:
Rendering of Text in Gnome-shell (and gedit) is broken. (May need to move bug
for harfbuzz or pango?). but working as expected with Search (with
gnome-shell), and Run dialog (Alt+f2)

example Text [क्रियाएँ]


Version-Release number of selected component (if applicable):
lohit-devanagari-fonts-2.5.3-2.fc19.noarch

gnu-free-sans-fonts-20120503-5.fc19.noarch
gnu-free-fonts-common-20120503-5.fc19.noarch
gnu-free-mono-fonts-20120503-5.fc19.noarch
gnu-free-serif-fonts-20120503-5.fc19.noarch

How reproducible:


Steps to Reproduce:
1. Login into Hindi Desktop
2. Check "Acitivies" Rendering
3. Copy (क्रियाएँ) Text
4. Paste in Gedit
5. Press Window (Super) Key and Paste Text in Search
6. Alt + F2 and paste Copied text
7. Run firefox and Paste copied text

Actual results:
Rendering is wrong in step 2 (gnome-shell), 4 (gedit), 


Expected results:
Rendering is correct for Step 5, 6, 7

Additional info:
1. If remove gnu-free-* fonts from system, rendering is fine
2. Bug #918478 is already fixed, but still issue is there for Rendering.



Few more results from terminal on desktop

If it's not occurring everywhere, I'm not convinced the bug is with the fonts,
but with something farther down.  Could you attach a screenshot(s) with
examples?

Screenshot for Issue

Blue Underline - Rendering is Correct
Red Underline  - Rendering has issue

(sorry for delay in screenshot)

--- Additional comment from Jon Ciesla on 2013-04-25 20:37:01 IST ---

Alright, based on that I'm guessing harfbuzz.

--- Additional comment from Jens Petersen on 2013-04-26 06:56:17 IST ---

Probably we should not be using GNU Free for Hindi then?

Alam: other Indic scripts/langs are not affected??

--- Additional comment from Jens Petersen on 2013-04-26 09:02:58 IST ---

Presumably switching gedit to Lohit Devanagari fixes the rendering there.

Actually doesn't seem to be any Preferences UI now in gedit.

FreeSans rendering issues with Harfbuzz NG

This is problem with FreeSans rather than Harfbuzz. Please check text 

"प्रविण सातपुते क्षत्रिय क्रियांये " with Lohit Devanagari for correct
rendering.

Its probem with Rakara feature, if time permits i will provide patch for this.

I can confirm Punjabi (Gurmukhi) has issues, other Pravin can confirm.

pref for gedit

Please click (or right click) on gedit icon (which is close to Activities in
gnome-shell) and you can get preferences.

need to have similar recipe for FreeSans like this for FreeSerif:

Modified lohit devanagari conf file

After modifying lohit fontconf now i am getting

$fc-match serif:lang=hi
$fc-match sans-serif:lang=hi
$fc-match monospace:lang=hi


But still gnome-shell "activities" showing me FreeSans in output. Just
wondering from where it is coming.

I will provide patch to fix this in upstream or Fedora. 

This issues is specifically for invalid rendering of some Devanagari syllable
using FreeSans.

patch to fix rendering issue.

I have reported this problem in upstream as well. So if upstream is quick we
can wait for there release, else will be good to build this with locale fedora
patch.

Hi, your friendly GNU FreeFont admin here.

This is a known problem, which has been repaired some time ago in SVN.

The 2012 release of GNU FreeFont was tested with Pango and Win XP, by native
speakers and by myself. The font shaping engine of Windows Vista and 7 is
substantially different from that of XP, and it was known at the time of the
previous release that this change resulted in wrong rendering in those systems,
much like the one described here.

Harfbuzz emulates these newer Windows shaping engines, and so the problem
arises there.

One of the main thrusts in FreeFont over the past year has been to re-engineer
the lookup tables to work with the newer font renderers.

As to when a new release will happen: I don't know -- soon, I hope.  Some
ranges of the font are not in a deliverable state at this time.  I'll renew my
efforts on this.

I'll continue the discussion in the GNU FreeFont bug report.

Cheers!

Hi Jon,

  I think next upstream release will take some more time. I checked with the
upstream svn for the fix of this bug. Patch given by me match with fix in
upstream.

  It will be good if you can build gnu-free-fonts with the patch provided in
comment #2, so that we can get gnu-free-fonts issues fixed release in Fedora
19.

  Spec file for quick build with above patch is available
http://pravins.fedorapeople.org/gnu-free-fonts.spec

Hi Pravin,

You are right in that the FreeFont release cannot be expected within the next
month or so.  There are just too many issues in progress at this time.

The patch is the right way to go.
