[metapost] Umlaute in labels

[Fieger, Andreas]

Klaus,

you use vardef showpoint(expr t, P)(text T) and  
assing the text T to a picture lab.

Can't you define vardef showpoint(expr t, P, T) and 
then use dotlabel.top(T, (P*u)) directly?

For me

vardef foo(expr p) =
  if picture p:
    label(p, origin);
  else:
    label(btex not a picture etex, origin);
  fi
enddef;

beginfig(1);
  foo(btex mein L\"ab\"ol" etex);
endfig;

works (or am I missing the point?)

Best,
Andreas
