strutheight and (german) umlauts

strutheight and (german) umlauts

[Peter Rolf]

Hi,

I just run into the problem, that \strutheight is lower than the height
of some german umlauts (ÄÖÜ).

% -----
\setupoutput[pdftex]
\mainlanguage[german]

\setupcolors[state=start]

\starttext
\showstruts

\def\FOO#1{\framed[frame=off,background=color,backgroundcolor=green]{#1\strut}}

\hbox{\FOO{AOU}\FOO{ÄÖÜ}}

\stoptext
% -----

Is this intended (and if so, why)?

I need this for several boxes with a mp overlay as background and
centered text. The height of the boxes is equal, so all text should be
placed on the same baseline. Currently I box the text and set the height
manually to \strutheight. But a more "global" solution would be prefered.
Should I define my own gfx strut or just add one of those umlauts to
\setfontstrut or ...? Dunno what is the best solution.

Greetings, Peter

(1) increase the lineheight (2.8ex by default) 
(2) change the height/depth ration (.72/.28 by default) 

it all depends on the font

I know not much about this stuff, so thanks for the helpful answer.

the .72/.28 and 2.8ex work quite wel for most fonts as well as math; they originate in the inrstex macro package that we used long ago (just before we started writing context, which for some time used snippets of the rather modular inrstex)
