Answer 1

You can add URI Encoding property to your connector.

In your Tomcat distribution's conf/server.xml file, find the connector definition for your HTTP protocol and add at the end of the connector URIEncoding="UTF-8" like so.

<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" URIEncoding="UTF-8"/>

Alternatively you can set encoding via system property -Dfile.encoding=utf-8

Answer 2

The Unicode version does not depend on the Tomcat version, but on the Java version. Do you use the same Java version for both Jetty and Tomcat?

And where in the code and how do you access the Unicode information? Maybe it helps to implement that part using IBM's icu4j, which can be updated independently of the Java version.

The problem is the pageEncoding UTF-8. I had to use other encoding in my jsp only when I use the emoji, the encoding that work for me is ISO-8859-8.
