回答1:

According to a comment on another question you need to upgrade to tomcat 8.0.15 (or higher) and enable the RFC 6455 cookie processor. Documented here: http://tomcat.apache.org/tomcat-8.0-doc/config/cookie-processor.html

Enable it in your conf/context.xml via:

<Context>
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor" />
</Context>

Use UTF-8 Encoding.

You can either set it globally:

java -Dfile.encoding=UTF-8

Or locally:

System.setProperty("file.encoding", "UTF-8");

byte inbytes[] = new byte[1024];
FileInputStream fis = new FileInputStream("the.location.of.your.cookie");
fis.read(inbytes);

Also, if you are editing the cookies manually, don't save Ä. Instead use the UTF-8 equivalent, which is

System.out.println("\u00c4");



Chars   Unicode
------------------------------
Ä, ä    \u00c4, \u00e4
Ö, ö    \u00d6, \u00f6
Ü, ü    \u00dc, \u00fc
ß       \u00df
