I too have a similar issue. My mapping looks pretty much the same. It looks like the analyzer is replacing the umlaut with a standard ascii character but also not keeping the umlaut. My use case is to allow for searches with or without the special characters. So "ju" and "jü" should both work. I'm trying to use the icu\_folder as well - does anyone have any insight or examples of this?

Thanks!
