[Zope] url_quote_plus inside of RESPONSE.redirect

Hello all I have a variable called "query" which contains a search query. For example:"mäßig Genügsam" (with german special characters ;-) With <dtml-var query url_quote_plus> I can use it inside of an anchor tag like this: <a href="/MyZCatalog/report?query=<dtml-var query url_quote_plus>"> But how do I get url_quote_plus in this case? <dtml-call "RESPONSE.redirect('/MyZCatalog/report?query='+query)"> In this case no special characters are "url_quoted". I know I could use javascript here, but I want to avoid this.
