Re: Greek font in Footnote problem

[Thomas A.Schmitz <thomas.schmitz@uni-bonn.de>]

First: thanks to Giuseppe and Hans for their suggestions! As soon as I  
have a bit more time, I will look into the \scantokens command and try  
and correct my Greek modules. However, I had a couple of minutes today,  
and it looks like the solution to Alan's problem is much simpler. In  
your sample, Alan, if you replace

\setupbodyfont[cmr, 10.5pt]

with

\setupbodyfont[cmr, 10pt] %or 11 pt or 12 pt

the file compiles cleanly, with Greek in the footnotes where it should  
appear. So, for the time being, it doesn't seem to be a problem with  
the catcode changes. If I'm not mistaken, this would have given weird  
characters, but the problem was that the font change was not done at  
all.

So: I had already mailed off-list to Alan that I thought the problem  
was with defining the new bodyfont. And I think this is right. In my  
definition for  the Greek fonts, I have this line:

\definebodyfont[4pt,5pt,6pt,7pt,8pt,9pt,10pt,10.5pt,11pt,12pt,14pt,14.4p 
t,16pt,18pt,20pt,22pt][rm][Gf=greeoxon sa 1.08]

So I would assume the following:

1. When the body font of the document is 10, 11 or 12 pt, the footnote  
body font is in one of the predefined sizes, i.e. 8, 9, 10, whatever.
2. When the body font is a weird number like 10.5, ConTeXt (or is it  
eTeX itself?) recalculates the size for  the footnote, which will be an  
even weirder number. Accordingly, the definitions in my file won't work  
anymore.

Thusly: I looked at the source to find out by which factor the font in  
the footnotes is scaled, but couldn't find out. So my questions: how is  
this font size calculated? Or is it possible to give a "blanket"  
declaration for font sizes in my file (there is something like <-> in  
LaTeX which means "all sizes," if memory serves right).

Thanks for the help!

Best

Thomas
