Foreign character set problem

Question

Hi Sergiusz, it looks like you are a character set guru. Maybe you would know how to solve my problem? I've got a working application under oracle xe, apache and embedded listener. I would like to switch to a new APEX listener with tomcat but there is a problem with a foreign character set. Existing pages with such characters are displayed correctly but if I type them in into an input filed they are not showing up correctly on the next page. This is done without even saving information in a database. I type in text in one field which is a source of an item on another page. These are character settings in my database.
SQL> select value from nls_database_parameters where parameter = 'NLS_CHARACTERSET';
VALUE
AL32UTF8
SQL> select value from nls_database_parameters where parameter = 'NLS_NCHAR_CHARACTERSET';
VALUE
AL16UTF16
Thanks,
Art

Hi Sergiusz, thank you for your help. After setting a URIEncoding to UTF-8 and some further research I was able to fix my problem. Here is the entire solution in case someone else needs it.
1.) Change $CATALINA_HOME/conf/server.xml and add
URIEncoding=UTF-8
<Connector port="8090" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>
2.) Copy $CATALINA_HOME/webapps/examples/WEB-INF/classes/filters/SetCharacterEncoding.class => $CATALINA_HOME/webapps/apex/WEB-INF/classes/filters
3.) Add the following into $CATALINA_HOME/webapps/apex/WEB-INF/web.xml file after the last </servlet-mapping> tag.
<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>filters.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Thanks,
