Strange spurious character

Strange spurious character

[Otared Kavian]

[-- Attachment #1: Type: text/plain, Size: 643 bytes --]

Hi Hans,

After having updated my installation of ConTeXt, I noticed the presence of a spurious « ß » character at the top of every document, or sometimes in the footer, or in the header.
Also in the example below the text is typeset with bold italic, even though there is no request for it.

Here is a minimal example:
%%%% begin bug-beta.tex
\definefallbackfamily[mainface][serif][palatino]
\definefontfamily[mainface][sans][palatino] 
\setupbodyfont[mainface]

\starttext

Why is there a « ß » LATIN SMALL LETTER SHARP S  above?

Why is the text in bold italic?

\stoptext
%%%% end bug-beta.tex

Best regards: OK

Hi Hans,

Thanks for the quick fix.
Indeed the spurious character does not show up anymore, but in the minimal example below the default body font seems to be set to bold italic, please see the attached PDF (I did not observe this in my real documents, but curiously it shows up in this minimal example): it may be that I am using a wrong font definition here. 
The version of ConTeXt is  2016.11.18 22:20 MKIV beta  fmt: 2016.11.18.

%%%% begin bug-beta.tex
\definefallbackfamily[mainface][serif][palatino]
\definefontfamily[mainface][sans][palatino] 
\setupbodyfont[mainface]

\starttext

Why is the text in bold italic?

\stoptext
%%%% end bug-beta.tex

I don't know,

\definefallbackfamily[mainface][serif][texgyrepagella]
\definefontfamily[mainface][sans][texgyrepagella]
\setupbodyfont[mainface]

\starttext

Why is the text in bold italic?

\stoptext

works ok here so you need to check what palatino gets selected (maybe 
you need to be more specific)

Re: Strange spurious character

[Otared Kavian]

Hi Hans,

Indeed with your solution, that is saying

\definefallbackfamily[mainface][serif][texgyrepagella]
\definefontfamily[mainface][sans][texgyrepagella]
\setupbodyfont[mainface]

or more simply saying

\setupbodyfont[palatino,12pt]

there is no problem. It seems that the issue comes from the use of

\definefontfamily[mainface][sans][palatino]

in the example I sent.
So I am going to use your way of defining the fontfamily.

Thanks again and best regards: OK

I can reproduce with the palatino on my system which comes in ttc-format.

The problem is that context adds only a single font from a ttc-font to 
the database
which results in weird results.

Clearing the font cache with "mtxrun --script cache --fonts --erase" 
helps sometimes
but the problem can appear when the font cache is updated.

Hi Wolfgang,

Thanks for your remark: indeed after issuing the command

	mtxrun --script cache --fonts —erase

the result is correct with palatino as the choice of font. 
I notice that the luatex-cache increases during the time: is there any reason for which the luatex-cache is not erased when updating? 

Best regards: OK

afaiks ttc subfonts get an entry in the name list (of course access by 
file is debatable then, in which case the first found match is used)

if you add fonts to the system with the same name you need to force a 
mtxrun --script font --reload --force
