Public bug reported: This bug was present in the implementation of USE up to Version 1.1.2 of HarfBuzz - https://github.com/behdad/harfbuzz/issues/180 records problem and fix in Version 1.1.3. The bug also affects the much-afflicted Tai Tham script, e.g. in the word ᩉ᩠ᩅᩯᩁ /wɛːn/ 'ring (n.)'. Unfortunately, LTS Ubuntu release 16.04 is still at Version 1.0.1 - there are no backports from Yakkety (Harfbuzz 1.2.7) or Zesty (Harfbuzz 1.4.2).
Potentially unsafe work-arounds include building HarfBuzz (e.g. Version 1.4.6) and replacing the sharable object libharfbuzz.so.0 with a user- generated sharable object. It is possible to backport from Yakkety oneself using the Firefox example in "Recommended alternative to pinning" at https://help.ubuntu.com/community/PinningHowto. Note that the final command is sudo apt-get -b source -t yakkety harfbuzz One then installs the corrected object by means of the command sudo dpkg -i libharfbuzz0b_1.2.7-1_i386.deb ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: libharfbuzz0b 1.0.1-1ubuntu0.1 ProcVersionSignature: Ubuntu 3.13.0-102.149-generic 3.13.11-ckt39 Uname: Linux 3.13.0-102-generic i686 ApportVersion: 2.20.1-0ubuntu2.9 Architecture: i386 CurrentDesktop: Unity Date: Fri Jul 14 22:21:04 2017 InstallationDate: Installed on 2010-12-28 (2390 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release i386 (20100816.1) ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.utf8 SHELL=/bin/bash SourcePackage: harfbuzz UpgradeStatus: Upgraded to xenial on 2016-11-19 (237 days ago) ** Affects: harfbuzz (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 third-party-packages xenial -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to harfbuzz in Ubuntu. https://bugs.launchpad.net/bugs/1704492 Title: Prebase vowels not moved to before consonants joined by virama To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/harfbuzz/+bug/1704492/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
