Hi Omar, I can not get it to work either, yet: >> * No content-encoding is specified by the resource >> >> I found no way to not specify an encoding for whatever I return in RESTXQ. >> If I don't specify anything it's UTF-8. it shows up as "; >> character-set=UTF-8"I did not find a way to specify no encoding.

Content-Encoding denotes how the content has been encoded (gzip, deflate, etc.) => https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding <https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Encoding> that’s not the character encoding (such as UTF8). So the GZIP handler not working correctly is most probably not due to the UTF8 Encoding you are seeing. Actually I did not get the GzipHandler working, even using the DefaultServlet ( => requests to /static) instead of BaseX’ RestXQServlet and I found this comment that states: > https://stackoverflow.com/questions/38635262/jetty-9-and-gziphandler > <https://stackoverflow.com/questions/38635262/jetty-9-and-gziphandler>The > implementation of Gzip support in Jetty is now based on a Container HTTP > Output Interceptor pattern.
