problem with pdftex-1.40.1 and Gentium ligatures

[Johan Sandblom]

[-- Attachment #1: Type: text/plain, Size: 911 bytes --]

When I moved from pdftex-1.30.5-2.2 (from texlive-base-bin
2005.dfsg.2-10 on debian) to pdftex-1.40.1 suddenly ligatures in
gentium exhibited erratic behavior: they appeared correctly (or, more
accurately, the letters appeared, they did not look like a proper
ligature) on screen in xpdf and acroread but did not print (there were
just empty spaces). On windows, the fi, fl, and ff combinations made
blanks, just as on the printer. Reverting to pdftex-1.30.5-2.2
corrected the problem. Gentium is from ttf-gentium 1.02-2 on debian
and the typescript I use is below. Perhaps my poor typesetting
knowledge has lead me wrong and the lack of true ligatures is the
actual problem?

Regards, Johan

Hi Johan,

If the only change is the pdftex version, than it sounds like this
is a pdftex bug. Any chance you can create a small standalone testfile?

Best, Taco

It took a lot of searching for a minimal case, apparently there are
many levels of interaction here. The file below has blanks for fi fl
ff when compiled with pdftex-1.40.1 but not with pdftex-1.30.5. Do you
need some parts of my tex/font setup as well?

no, but it may be related to a bug in vf handling that has been resolved 
by now (new version of pdftex coming)

For the time being I simplified my design and removed the use of Zapf
Chancery, and there is no problem.

I am trying to work this out, but I obviously miss the gentium
font files (metric and map files, as wel as the actual fonts).
I can get the ttfs from the sil site, but where did the tfms
and map files come from?

Best,
Taco

Re: problem with pdftex-1.40.1 and Gentium ligatures

[Johan Sandblom]

Sorry, neglected to mention (it was long ago and I had forgotten), I
installed it with texfont

texfont --ma --in --ve=sil --co=gentium --fontroot=/usr/share/texmf
--afmpl [--en=ec]

hmm, can't remember if it was /usr/share on the end

Thank you for your efforts

Btw: The -recorder switch of pdftex/web2c (don't know how to use that
with texexec) will write a list of all files used by pdftex (including
fonts) to a file. And if you put all these files in the same directory
as your input file, pdftex will use those, so you don't have to fiddle
with texmf-*.

Like so:

  texexec --passon=-recorder file.tex

The --passon feature had lapsed in the transition from perl to ruby
texexec, but Hans and Taco fixed it in one of the recent ConTeXt
releases.  I now use it all the time to get compiler-like error msgs:

  texexec --passon=-file-line-error ...

filtering the output through

  egrep -i -A 4 '^([^ :]+:[0-9]+: |output written.*pages)'

to select the error lines and a bit of context, so to speak.

This seem to be fixed with 1.40.3 release of pdftex .
