Too small { in the fourier font

Too small { in the fourier font

[Mikael Persson]

Hi all,

when using the fourier font I get the wrong size of the opening { in
the \startcases \stopcases environment. The following small example
shows the problem and it fails both at my place and at
http://live.contextgarden.net/

%%%%
\usetypescript[fourier][ec]
\setupbodyfont[fourier,10pt]

\starttext
\startformula
f(x)=
\startcases
\NC 1 \MC x>0\NR
\NC 0 \MC x<0\NR
\stopcases
\stopformula
\stoptext
%%%%

I run the minimal ConTeXt, from 8th of august:
ConTeXt  ver: 2007.08.08 14:35 MKII  fmt: 2007.8.26  int: english/english

Moreover, if I comment the first lines out above, the opening { is
"stretched" correctly (in latin modern).

Any ideas?

Best regards, Micke P

An easy workaround, use texnasi encoding :-)

\usetypescript[fourier][texnansi]

Maybe a bug somewhere, but math fonts are like a black box to me.

Thanks, but if I try that, I dont get the fourier fonts at all, but
the lm ones (both home and at live.contextgarden.net).

Sorry, did not notice that using texnansi encoding with fourier 
switches to lm. Probably the result of a fallback.

I wonder if this is the missing design size in lm fonts problem.   Using
ConTeXt ver: 2007.08.23 the sizes look OK for me.

Re: Too small { in the fourier font

[Mikael Persson]

Update:

This seems to be a problem that is introduced after 20070403. I am
running that version at work (minimal installation on linux there
aswell), and there it looks OK with the fourier fonts.

Another problem is given by $\hat f$. In the older one it looks OK,
but in the newer the hat is placed wrongly. New minimal example that
shows both these problems:

%%%%
\usetypescript[fourier][ec]
\setupbodyfont[fourier,10pt]

\starttext
\startformula
\hat f(x)=
\startcases
\NC 1 \MC x>0\NR
\NC 0 \MC x<0\NR
\stopcases
\stopformula
\stoptext
%%%%

Any ideas? I don't want to switch back to ver 20070407 if it is not necessary...

There have been some major changes in font handling.   It turned out that
the lm fonts didn't define a design size but apparently it didn't matter until
quite recently, and then more recently a workaround was added.  I wouldn't
be surprised to see the problem in other fonts either because they use lm
for some glyphs or because they were created using the same toolchain.

I'd try the latest version first.  Normally I have my systems
configured with a separate
texmf-cont tree that I link to cont-tmf-<date> so I can very quickly
switch versions.

indeed, the tex gyre fonts etc also suffer from this but in many cases 
they default to 10

the lm/gyre authors are notified and will sort it out

Thanks for your replies. The lm/gyre authors does not take care of the
fourier fonts, right? What does this mean if one wants to use the
fourier fonts?
