agreed. Although WAHtmlErorHandler doesn't implement #handler. So I 
ended up with this:


         response

             internalError;

             contentType: ((WAMimeType textHtml) charset: self requestContext charSet);


Thanks for your tip.

For the record: if the error handler gets rendered as a child in the 
component tree, that setting of charset is not necessary, but it is 
necessare if the Error handler is the main component. Special characters 
might be wrong then if the server side is not using utf-8. It may even 
have such strange effects like a Firefox on Mac using a 1252 code page 
(which I thought is Windows specific...).
