Hi Martin,

we have discussed this problem a year ago. In that time I solve it just 
writing '{}' in each title where was needed, like

   \chapter{Dobré{} ráno}

Now I have cooked an automatic solution. It is not optimal (effective) 
but working. The only needs is to redefine

   \def\numcharacter#1{\char#1{}}
   \let\dochar\numcharacter

and to load appropriate encoding file once more. Since it is banned a 
new macro \reuseencoding was introduce:

For Hans:
It would be nice if this feature was enabled in a standard distro. 
Perhaps you will find some more optimal solution...

-------------------------------------------------------
\unprotected
\def\doreuseencoding#1%
   {\letvalue{\c!file\f!encodingprefix#1}\empty
    \makeshortfilename[\f!encodingprefix#1]%
    \startreadingfile
    \readsysfile\shortfilename
      {\showmessage\m!encodings2{#1}}
      {\showmessage\m!encodings3{#1}}%
    \stopreadingfile}
\def\reuseencoding[#1]%
   {\processcommalist[#1]\doreuseencoding}


\def\numcharacter#1{\char#1{}}
\let\dochar\numcharacter

\reuseencoding[ec]

\enableregime[latin2]

\starttext
\writetolist[chapter]{1}{Dobré ráno}
\expanded{\writetolist[chapter]{2}{Dobré odpoledne}}

\placecontent
\stoptext

Simple \expandafter is not sufficient, more \expandafters is dirty trick and full expansion (\expanded) leads to TOC entry problem. In TeX source this cannot occur (or can occur in strange situations :-), in XML source this is almost rule.
