changing from oldstyle to upright

changing from oldstyle to upright

[Idris Samawi Hamid]

Dear consortium,

Switching to oldstyle is easy:

\usetypescript [modern][\defaultencoding]
\usetypescript [map]   [latin-modern-os] [\defaultencoding]
\setupbodyfont [modern]

But how do I locally switch back to upright? Declaring

\usetypescript [map]   [latin-modern]    [\defaultencoding]

does nothing. Basically I want to have something like

\def\UP{\switchtobodyfont[lmrup]}

for local effects. I tried

\definetypeface [lmrup] [rm] [serif] [latin-modern] [default] 
[encoding=texnansi]

to no avail as well. Test file attached

Thnx in advance!
Idris

I don't think you can, actually. There are no metric files
for oldstyle in the latin modern distribution, only an encoding
vector (and .map).

Pdftex either uses entries from the 'lining' map file, or from
the 'oldstyle' mapfile, but it has no way of distinguising
between the two (the fonts have the same metrics).

The reverse of the old oldstyle trick should work though:

   \def\liningfigures#1{\mathematics{#1}}

Cheers, Taco

So once a map/encoding is defined for a given font/tfm set it cannot be 
changed by declaring another map; interesting.

Yes! I should have thought of that!

As always, thnx a million!
