[Bug 1639513] Re: Pango-WARNING **: shaping failure, expect ugly output

[Sapa Holliday]

I am using libpango-1.0-0, version 1.38.1-1 and can't open or convert a
.swf adobe flash file.

I notice that you are using ... libpango1.0-0:amd64_1.38.1-1

Yet you are also using     .... libpango-1.0-0:amd64_1.38.1-1

You might have a conflict there

Title:
  Pango-WARNING **: shaping failure, expect ugly output

Status in pango1.0 package in Ubuntu:
  Confirmed

Bug description:
  Exactly as reported in
  https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1396048, which
  was marked as "Invalid" because it is reporting to the wrong package.

  The problem from that post:

  Console:

  $ evince

  (evince:8959): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'Ubuntu 11'
  (evince:8959): Pango-WARNING **: font_face status is: out of memory
  (evince:8959): Pango-WARNING **: scaled_font status is: out of memory
  (evince:8959): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Ubuntu 11', text='●'

  As for mine, it is basically the same:

  (process:13924): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is '微软雅黑 9'
  (process:13924): Pango-WARNING **: font_face status is: file not found
  (process:13924): Pango-WARNING **: scaled_font status is: file not found
  (process:13924): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='PangoFcShapeEngine', font='微软雅黑 9', text='Ayg'

  As the result,

  For the original reported, "some font and only displays squares in
  menus, text is displayed okay,", but for me, everything are displays
  as squares in menus, including English texts.

  However, my rxvt-unicode, which uses the 微软雅黑 font, display correctly
  without any problem.

  The cause of the problem, is also exactly as described in the original
  post:

  It happens because of symlinks from /usr/share/fonts to a different
  partition. For the original reporter, some fonts are symlinked, and
  for me 微软雅黑 is symlinked to a different partition. Thus his is missing
  some text, while I'm missing everything.

  symlinking fonts to a different partition is quite harmless in my
  view, and Pango should not treat them any differently.

  This only happens since Ubuntu 16.04. In Ubuntu 15.10, it was OK.

  My current Pango related packages that exhibit such problem:

   gir1.2-pango-1.0:amd64_1.38.1-1
   libcogl-pango20:amd64_1.22.0-2
   libpango-1.0-0:amd64_1.38.1-1
   libpango-perl_1.227-1
   libpango1.0-0:amd64_1.38.1-1
   libpangocairo-1.0-0:amd64_1.38.1-1
   libpangoft2-1.0-0:amd64_1.38.1-1
   libpangomm-1.4-1v5:amd64_2.38.1-1
   libpangox-1.0-0:amd64_0.0.2-5
   libpangoxft-1.0-0:amd64_1.38.1-1

  Please look into it. Thx.
