Umlaute in Formula

Umlaute in Formula

[Florian M. Baudach]

Dear all,

I need german Umlaute in my formulas of my master thesis.

I used \ddot{a} for ä. It had worked fine until I updated Context
yesterday :-(. Since that update I only get an crossed a with an accent,
but no ä.

I still use MKII.

Has anybody a solution for my little problem?
Thanks

Greetings and Happy Eastern
Florian Baudach

Hello Florian,

(I fear to update ConTeXt now that you mention it, so I won't try out
your example :) :) :)

Do you need "a umlaut" or do you need a double differential (d^a/dt^2)?

I just wanted to say that if you need ä as "a umlaut" in formulas, you
would probably want to use $\text{bär}$ rather than $\rm b\ddot ar$ in
such cases. But if there's indeed a problem, it needs to be fixed
anyway.

Here

\starttext
$\ddot a$
\stoptext

works fine (see attached pdf). I am using

ConTeXt  ver: 2009.04.13 14:45 MKII  fmt: 2009.4.13  int: english/english

Can you create a minimal example that fails?

Yes. I think I have found the problem:

\starttext
\placeformula
\startformula
 Knappheit = \frac{Stimmen\ f \ddot{u}r\ erstplatzierte\ Partei -
Stimmen\ f\ddot{u}r\
 zweitplatzierte\ Partei}{G\ddot{u}ltige\
 Stimmen}
\stopformula
\startformula
\ddot a
\stopformula
\usetypescript[times][ec]
\setupbodyfont[times,11pt]
\placeformula
\startformula
 Knappheit = \frac{Stimmen\ f \ddot{u}r\ erstplatzierte\ Partei -
Stimmen\ f\ddot{u}r\
 zweitplatzierte\ Partei}{G\ddot{u}ltige\
 Stimmen}
\stopformula
\startformula
\ddot a
\stopformula
\stoptext

When I use the Default-Font, then \ddot{} works fine. But when I switch
to times, then I get an very strange symbol.
(I wasn't able to attach the output of my example, because it was to big
:-()

This problem has started when I updated to:
ConTeXt  ver: 2009.04.10 18:02 MKII  fmt: 2009.4.12.

Before the update \ddot{} worked also with times.

Is there an solution?

Greetings
Florian Baudach

Yes, use
    Knappheit = \frac{\text{Stimmen für erstplatzierte Partei} ...

but I agree that it needs to be fixed. I didn't manage to convince
Hans to fix this so far, so maybe you'll have more luck with it :) :)

This has been a known problem for a few months (my fault, sorry), but
I was sure that it has already been fixed a while ago.

------

I would suggest adding the file q-8r.enc to
   /fonts/enc/dvips/context/
and replace
   "encqrm ReEncodeFont" <q-rm.enc
with
   "encq8r ReEncodeFont" <q-8r.enc
everywhere in original-youngryu-px.map and original-youngryu-tx.map.

Problem with MyItemCommand

[bbvogel]

Dear all,


Is the following example still valid for MKIV or is it a bug?

%from:
%tex/context/base/strc-itm.tex
%

\def\MyItemCommand#1{{\bf#1}\quad}
\setupitemgroup[itemize][command=\MyItemCommand]

\starttext
\startitemize
\item {test} is this okay?
\item {test} is this okay?
\item {test} is this okay?
\stopitemize

\stoptext

This is the error I see:

This is LuaTeX, Version snapshot-0.38.0-2009041013 (Web2C 7.5.7)
(myitemcommand.tex

ConTeXt  ver: 2009.04.15 12:15 MKIV  fmt: 2009.4.15  int: english/english

.............
..........

! Argument of \MyItemCommand has an extra }.
<inserted text>
                \par

                   }
