UTF-8 encoding in JSP page [duplicate]

Answer 1

Thanks for all the Hints. Using Tomcat8 I also added a filter like @Jasper de Vries wrote. But in the newer Tomcats nowadays there is a filter already implemented that can be used resp just uncommented in the Tomcat web.xml:

    setCharacterEncodingFilter
    org.apache.catalina.filters.SetCharacterEncodingFilter
    
        encoding
        UTF-8
    
    true

...

    setCharacterEncodingFilter
    /*

And like all others posted; I added the URIEncoding="UTF-8" to the Tomcat Connector in Apache. That also helped.

Important to say, that Eclipse (if you use this) has a copy of its web.xml and overwrites the Tomcat-Settings as it was explained here: Broken UTF-8 URI Encoding in JSPs
