new font installation and missing ligatures

new font installation and missing ligatures

[Bill McClain]

I have installed a new font (Adobe Sabon) using texfont and have added
the procedure and examples to my beginner's help page at
http://home.salamander.com/~wmcclain/context-help.html.

Your comments and corrections are always welcome.

The font is working well, except for one problem: no ligatures (fi, fl,
``. ''. --. ---). The really strange aspect is that the ligatures _are_
displayed by the \showligatures macro used by \ShowFont, but are _not_
displayed in my own sample code. This is odd because looking at
\showligatures, it just specifies the ligatures as plain text input.

I can access the ligature gylphs by character number, for example by:

\def\Endash{\getglyph{Serif}{\char150}}
\def\Emdash{\getglyph{Serif}{\char151}}
\def\Fl{\getglyph{Serif}{\char8}}
\def\Fi{\getglyph{Serif}{\char12}}
\def\OpenDquote{\getglyph{Serif}{\char147}}
\def\CloseDquote{\getglyph{Serif}{\char148}}

These ligature macros are working: \ae, \AE, \oe, \OE.

Any ideas?

-Bill

this sounds strange, since lig building is done deep down into tex, and if 
\showligatures works, then i would expect other usage to work as well

how does the smallest non working example code looks like?

Stranger and stranger. \showligatures displays the correct glyphs when
called by \ShowFont, but does not show the glyphs when I call it
directly in my job.

Here is demo.tex:
***
\usetypescriptfile[type-sabon]
\usetypescript[Sabon]
\setupbodyfont[Sabon, 30pt]
\noheaderandfooterlines

\def\Endash{\getglyph{Serif}{\char150}}
\def\Emdash{\getglyph{Serif}{\char151}}
\def\Fl{\getglyph{Serif}{\char8}}
\def\Fi{\getglyph{Serif}{\char12}}
\def\OpenDquote{\getglyph{Serif}{\char147}}
\def\CloseDquote{\getglyph{Serif}{\char148}}

\starttext
\startlines
>plain
`` fi fl '' -- ---

>glyphs
\OpenDquote\ \Fi\ \Fl\ \CloseDquote\ \Endash\ \Emdash

>showligatures[Serif]
\showligatures[Serif]

>macros
\ae\ \AE\ \oe\ \OE\
\stoplines
\stoptext
***

And its result: http://home.salamander.com/~wmcclain/demo.pdf

Here is the result of texnansi-adobe-sabon.tex as generated by texfont.
It renders the existing ligatures correctly. (I've commented out 3 of
the 4 fonts):
