typescript and font features bug?

[-- Attachment #1.1: Type: text/plain, Size: 1255 bytes --]

Hi all,

I am using the latest minimal and try to compile the following two files
with luatex. The second file, using typescript and font features together,
get a serious problem with the final pdf: punctuation centered unexpectedly
in lines. For the first files, with no font features specified, it is OK. I
do not know whether someone else can replicate this problem. But it
happended on my laptop. All compiled are attached in this email.

%FILE1: test1.tex
\starttypescript[serif][myserif][name]
\definefontsynonym[Serif][MinionPro-Regular][]
\stoptypescript

\definetypeface [myserif] [rm] [serif] [myserif]   [default]
\usetypescript[myserif]
\setupbodyfont[myserif,rm,12pt]

\starttext
\input zapf
\stoptext


%FILE2: test2.tex
\definefontfeature[minion][language=dflt, script=latn, mode=node,
                           frac=yes, onum=yes, kern=yes, liga=yes, dlig=yes,
                           protrusion=quality, expansion=quality]
\starttypescript[serif][myserif][name]
\definefontsynonym[Serif][MinionPro-Regular][features=minion]
\stoptypescript

\definetypeface [myserif] [rm] [serif] [myserif]   [default]
\usetypescript[myserif]
\setupbodyfont[myserif,rm,12pt]

\starttext
\input zapf
\stoptext

\definefontfeature[minion][language=dflt, script=latn, mode=node,
                            frac=yes, onum=yes, kern=yes, liga=yes,

\usetypescript[myserif]

\setupalign[hz,hanging]
\starttext
\input zapf
\stoptext

works ok; i don't have minion here (at least not an open type variant) 
so i cannot test that font

it has to be applied very selectively if only because the contextual

for me it makes such features rather useless and i'll probably cook up

It seems that the problem is only happened to my laptop. But I am sure that
the minimal was properly installed. Maybe is it a rpwt!

well, rpwt is not an international word. I think you should wait for your rp
coming and reinstall it.

Re: typescript and font features bug?

[Yue Wang]

I can confirm it is related to the frac featue.
The fonts in Acrobat Reader work ok.
However, Adobe FontFolio version appears to produce the problem.
Moreover, Adobe Brioso has the same problem.

Maybe that's why text in The Elements of Typographic Style disable the
dlig feature?
(In fact I love them and always enable dlig in my documents)

But it is strange that other engines render it well...

BTW, all Adobe Fonts have  a bug: they puts ligatures like Th into the
liga feature, not dlig.

I know why now: I have two different copies in texmf-fonts and osfontdir...

at some point i will provide an interface to correct for such errors; 
after all, font vendors have no 'bug fixing' policy

>> But it is strange that other engines render it well...

maybe other engines know about the bugs -)

other than in acrobat
