I'm back to investigating why Context is not displaying ligatures from my new Adobe Sabon font. I've discovered something else which may be a clue: Context and plain pdftex differ in the glyphs they generate from the same font file. I presume this is caused by some improper definition at my end, but I don't know how to diagnose it.
In the jobs below, simple-p.tex is just plain tex. Note (a) the ligatures don't work, (b) but the glyphs exist and can be referenced by number, (c) certain (but not all?) accented characters are being composed rather than using the proper glyphs. This is particularly noticeable in the accented "A" glyphs. PDF file: http://home.salamander.com/~wmcclain/simple-p.pdf. The Context version of the same job is simple-c.tex. (a) and (b) are as above, but for (c) it looks as if Context uses the correct glyphs rather than composing the chars. PDF file: http://home.salamander.com/~wmcclain/simple-c.pdf. What does Context know that plain pdftex doesn't? Finally, the sample file produced by texfont does produce the correct ligatures: http://home.salamander.com/~wmcclain/texnansi-adobe-sabon.pdf. I'm using: pdfeTeX, Version 3.14159-1.00a-pretest-20010806-2.1 (Web2C 7.3.3.1) (format=cont-en 2002.3.1) 8 MAR 2002 10:26 ConTeXt ver: 2002.2.25 fmt: 2002.3.1 int: english mes: english The plain tex file: * * * \pdfmapfile{+texnansi-adobe-sabon.map} \def\Fi{\char12} \def\Fl{\char8} \def\OpenDquote{\char147} \def\CloseDquote{\char148} \def\Endash{\char150} \def\Emdash{\char151} \font\sabon=texnansi-raw-sar at 60pt \sabon fi fl `` '' -- --- \Fi\ \Fl\ \OpenDquote\ \CloseDquote\ \Endash\ \Emdash \`A \char192 \'A \char193 \^A \char194 \~A \char195 \"A \char196 \AA \char197 \AE \char198 \c C \char199 \`a \char224 \bye * * * The Context file: * * * \def\Fi{\char12} \def\Fl{\char8} \def\OpenDquote{\char147} \def\CloseDquote{\char148} \def\Endash{\char150} \def\Emdash{\char151} \usetypescriptfile[type-sabon] \usetypescript[Sabon] \setupbodyfont[Sabon, 60pt] \starttext \noheaderandfooterlines fi fl `` '' -- --- \Fi\ \Fl\ \OpenDquote\ \CloseDquote\ \Endash\ \Emdash \`A \char192 \'A \char193 \^A \char194 \~A \char195 \"A \char196 \AA \char197 \AE \char198 \c C \char199 \`a \char224 \stoptext * * * -Bill
