Hi there,
As Aditya mentioned in a former posting (*) that "\text{ ... }" should scale properly when used as super- or subscript, I have prepared a minimal example to demonstrate that it doesn't. In my document I have switched from "\text{ }" to "\normal", which works.
Kind regards,
Andreas

Hello,
I generally use \mathrm{} (maybe this is a leftover from LaTeX
practice), and this works fine.

Hi Alan,
thanks for your help. That's indeed an option, but not much of a difference to using "\normal" I suppose.
In addition, "\text" has the nice feature of preserving the space character, which makes it very useful for lazy people (of course I can add "\," and friends but...).
Cheers,
Andreas

There is another bug with \text.
{\switchtobodyfont[sans] $\text{sans}$}
does not switch to sans font. Both the incorrect scaling and wrong font
switch can be corrected by restoring the old definition of \text in
math-ini.mkiv. Based on the comments in that file, this will come at a
high penalty on speed. (Slow but correct is better than fast but wrong!)

Actually, the bug is with \setcurrentfontbody
\starttext
ABC \hbox{\setcurrentfontbody{\scriptscriptface} Testing} DEF
\stoptext
The above works correctly in mkii but not in mkiv. I really don't
understand what \setcurrentfontbody is supposed to do. In Mkii it scales
the bodyfont if \scriptface or \scriptscriptface is used as an argument;
but does not work for any other value (e.g. \setcurrentfontbody{20pt}). In
MkIV it does not do anything.
There is also a bug in the definition of \text in mkii. In strc-mat.mkii,
we should have
\def\domathtext#1%
{\mathchoice
{\dodomathtext\displaystyle \textface {#1}}%
{\dodomathtext\textstyle \textface {#1}}%
{\dodomathtext\scriptstyle \scriptface {#1}}%
{\dodomathtext\scriptscriptstyle \scriptscriptface{#1}}}
Notice \scriptsctlye and \scriptscriptstyle instead of \textstyle in the
last two cases. If \setcurrentfontbody is fixed in mkiv, then the
definition in MkIV also needs to be changed in a similar manner.
Aditya

I don't understand the fix, but it gives the correct output.

hm, given your involvement in math you should study it -)
it boils down to the fact that in luatex we can actually ask what the
upcoming style can be (text, script, scriptscript)
normally a choice means 4 times processing and tex will use one only,
while in this case i could write \text in a way that processes only once
(so, way faster as we only have 1 bodyfont switch now)
