New combinations that are not used regularly and has been included into the Font TC. Therefore, considered as lower priority which can wait till 5.1.0. -- Additional comment from caolanm on 2007-01-04 03:39 EST -- Looking at the similar icu bug and then some comparison against kde which is mentioned as being correct here I have the two short sample sequences of... a) 0D31 + 0D4D + 0D35 b) 0D31 + 0D35 + 0D4D a is rendered the same in gedit and kedit b is rendered the same as a for gedit, but differently for kedit. It looks to me that qt takes the sequence, breaks it into chunks of syllables, then takes each chunk and reorders it and then applies the gsub to each chunk and renders each chunk. While icu (and probably pango) takes the sequence, breaks in into chunks of syllables, reorders the chunks. sticks the chunks back together into a sequence. Applies the gsub to the new sequence and renders it. i.e. for qt 1) 0D31 + 0D4D + 0D35 1.1) chunk of "0D31 + 0D4D + 0D35" 1.2) reorder -> order unchanged 1.3) gsub and render 2) 0D31 + 0D35 + 0D4D 2.1) chunk of "0D31" 2.2) reorder -> order unchanged 2.3) gsub and render 2.4) chunk of "0D35 + 0D4D" 2.5) reorder -> "0D4D + 0D35" 2.6) gsub and render for icu/(pango ?) 1) 0D31 + 0D4D + 0D35 1.1) chunk of "0D31 + 0D4D + 0D35" 1.2) reorder -> order unchanged 1.3) gsub and render 2) 0D31 + 0D35 + 0D4D 2.1) chunk of "0D31" 2.4) chunk of "0D35 + 0D4D" 2.5) reorder -> "0D31 0D4D + 0D35" 2.6) gsub and render so for icu/pango 1 & 2 are the same, and are the same as 1 for qt, which for 2 qt has a different result than pango.
I wrote a patch for fixing bug238896, bug223169 and bug223170. And I modified indic_shape_engine( ) in this patch, let it handle one by one syllable, not handle all syllables together. It can fix the three bugs only by this way. The patch is below: https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=156846
Problem still exists with 0D21 + 0D4D + 0D31 + 0D48 + 0D35 + 0D4D (ഡ്റൈവ്) Pango version: pango-1.19.3-1.fc9 Thanks Ani
This is yet to be fixed. Appreciate quick response. Thanks Ani
There is slight error in the combination mentioned in comment#2. The correct combination is: 0D21 + 0D4D + 0D30 + 0D48 + 0D35 + 0D4D (ഡ്രൈവ്)
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
requested by Jens Petersen (#27995)
Problem for Telugu as well as per http://bugzilla.gnome.org/show_bug.cgi?id=579398
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Parag, Pravin: could you check status of this please.
