I started to edit an old document with capitalized headings. Making the headings was rather difficult (as can be seen on this list about a year ago), and now it seems to have broken again.

I have:

\setuphead[title]
  [page=yes,
  before={\strut\blank[5*big]},
  after={\textrule\blank},
  align=middle,
  style=\tfb,
  textcommand=\WORD
  ]

This worked fine in the past. Not anymore:

! You can't use `\relax' after \the.

Using the trivial solution (\uppercase) does not work because with a non-il1 regime it does not handle the accented characters (A umlat, O umlaut) correctly. I use UTF, as it contains all the characters I need.

So, what has changed in the \WORD? It works \WORD{fine} within text but not in the headings.

TIA,
