Description Han-Wen Nienhuys 2006-02-01 19:07:13 EST
Description of problem:

The AFM file for century schoolbook (c059013l.afm) contains a ligature for N+o, 

  C 78 ; WX 815 ; N N ; B 19 -14 794 722 ; L o afii61352 ;

when converting this font to TTF, this results in pango making a strange 
substitution in words like "November".

I couldn't work out who the upstream maintainer is, so I'm posting the bugreport

Version-Release number of selected component (if applicable):

Comment 1 Han-Wen Nienhuys 2006-02-02 09:31:56 EST
George Williams notes that this is probably a remnant of a bug in a very old
fontforge version. Regenerating said fonts from their fontforge sources should
fix this.

BTW, have you given any though to shipping TTF files iso. Type1 files for these
fonts? Then Pango and freetype would be able to do kerning and ligature handling
out of the box.
Comment 2 Han-Wen Nienhuys 2006-12-14 07:19:11 EST
Hello, anybody there?

there is also a bogus T + M -> trademark-symbol ligature is the Century
Schoolbook AFMs.
Comment 3 Christian Iseli 2007-01-19 19:56:26 EST
This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Comment 4 Han-Wen Nienhuys 2007-01-21 07:58:55 EST
The problem is still there. You can simply grep the AFM to check.

Fedora apologizes that these issues have not been resolved yet. We're
sorry it's taken so long for your bug to be properly triaged and acted
on. We appreciate the time you took to report this issue and want to
make sure no important bugs slip through the cracks.

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.

If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If
you are unable to do this, please add a comment to this bug requesting
the change.

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

The process we are following is outlined here:

We will be following the process here:

This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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 '8'.

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 8'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 8 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: 
Comment 8 Bug Zapper 2009-01-09 01:55:29 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
