1/ I just copy-paste that symbol into search string.

2/ use expression: ${literal('…'):unescapeXml()}

3/ you can replace char with script (groovy)

def ff = session.get()
if(!ff)return
ff = session.write(ff, {rawIn, rawOut->
    rawIn.withReader("UTF-8"){reader->
        rawOut.withWriter("UTF-8"){writer->
            reader.transformChar(writer){ch-> ch==(char)'\u0085' ? '' : ch }
        }
    }
} as StreamCallback)
session.transfer(ff, REL_SUCCESS)
