definetypeface vs math symbols

definetypeface vs math symbols

[Ralf Schmitt]

Hi all,

what is the correct way to use another font in context? We use 
definetypeface and setupbodyfont (without really knowing what's going 
on...just copied from some example we found). When I uncomment the font 
statements in the following example, the Sigma symbol becomes a little 
circle and the the bar is rendered through z not above it?

TIA,
- Ralf


\starttext

%\definetypeface [charter] [rm] [serif] [charter] [default] [encoding=ec]
%\definetypeface [charter] [tt] [mono] [charter] [default] [encoding=ec]
%\setupbodyfont [charter, 9pt]

$ \Sigma $
$ |z|=|\bar{z}| $

\stoptext

Try adding the line

\usetypescript[serif][charter][ec]

at the beginning.

[BTW: your minimal example was almost visible; next time, make a  
bodyfont of 5pt]

I thought about making a comment on this remark. I tried 0pt font size, 
didn't work. Then I tried 1pt font size. And the funny thing is:
With 1pt font size the output is good!!!(also with 2pt and 3pt, but not 
with 4pt or up, with or without the \usetypescript command.).

Any insights? Am I going insane?

OK, this was just a joke, but it might help us. Looks like ConTeXt  
can't find the math font for defined sizes. Could you try two things  
(in turn, not at the same time):

1. define the math font as well:
\definetypeface [charter] [mm] [math] [modern] [default] [encoding=ec]

and see if this solves your problem.

2. In the file $TEXMF/tex/context/user/cont-sys.rme (or cont-sys.tex,  
if you have that file already), uncomment the line

\resetmapfiles \usetypescript [map] [base] [all]

save the file to cont-sys.tex, run texhash (or sudo texhash,  
depending on your setup) and see if this helps.

Your file compiles fine here, no problem at any size.

This works.

I've tested it on 3 machines and it didn't work on any of those (ubuntu 
dapper, debian testing, freebsd).

Many thanks,

Until one tries to use a bold font with \bf. This is the complete list 
of commands I use to circumvent that problem:

\usetypescript[serif][charter][ec]
\definetypeface [charter] [it] [italics] [modern] [default][encoding=ec]
\definetypeface [charter] [bf] [bold] [modern] [default] [encoding=ec]
\definetypeface [charter] [mm] [math] [modern] [default] [encoding=ec]
\definetypeface [charter] [rm] [serif] [charter] [default] [encoding=ec]
\definetypeface [charter] [tt] [mono] [charter] [default] [encoding=ec]
\setupbodyfont [charter, 11pt]


(Just to keep the archives complete...actually I don't understand what 
I'm doing (wrong?) here.)

\definetypeface [charter] [it] [italics] [modern] [default][encoding=ec]
\definetypeface [charter] [bf] [bold] [modern] [default] [encoding=ec]

does not make sense, 

\usetypescript[serif][charter][ec]
\definetypeface [charter] [rm] [serif] [charter] [default] [encoding=ec]
\definetypeface [charter] [mm] [math] [modern] [default] [encoding=ec]
\definetypeface [charter] [tt] [mono] [charter] [default] [encoding=ec]

\setupbodyfont [charter, 11pt] % rm si default since defined first 

or 

\setupbodyfont [charter, 11pt, rm] 



\setupbodyfont [charter, 11pt]

and what is surprising to me: order does matter here. If I put the 
definetypeface for math mode command at the front, {\bf bold} does not 
work anymore.

indeed, this is because the first one defined is the default (think of typefaces that only have ss, like optima) 

so, this may work when rm, tt or ss is defined first 

  \setupbodyfont [charter, 11pt]

but this is more robust 

  \setupbodyfont [charter, rm, 11pt]
