[NTG-context] accessibility of PDF (inter word space

Hello, I am very new in Context and have my first Problems. I read a lot, but can't find the solution. I try to produce accessible PDF. One Point is, that they have to be reflowed in a PDF-Viewer. But if I reflow my documents, there are no interwordspaces. I know that there is no space-character in Tex. I found an work-around for pdftex with an patch. \pdfmapline{+dummy-space https://freundschaftswerbung.gmx.de
