I am using querybuilder to read the properties of some text components. If I enter UTF8 chars (e.g ü) into the Adobe author editor (and I can see from the page source that its set to UTF8), I get ISO-8859-1 out.
When I get the ValueMap from the component in a servlet, I write the results to a file, and to the servlet response writer also. In the file, if I open it as a ISO-8859-1 I see ü. If i open it as a utf8 file (in VS code), i get a back "?". In postman I see a black "?" and also on the resultant webpage (which has utf8 set in the header).
