So I have followed your suggestion and have extended the src/main/webapp/WEB-INF/web.xml with: <?xml version="1.0" encoding="UTF-8"?> <web-app metadata-complete="false" version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd";> <servlet> <servlet-name>WordsServlet</servlet-name> <servlet-class>de.afarber.WordsServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>WordsServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <mime-mapping> <extension>js</extension> <mime-type>text/javascript;charset=UTF-8</mime-type> </mime-mapping> </web-app> Unfortunately the URL still returns the headers without "UTF-8" in there: HTTP/1.1 200 OK last-modified: Tue, 03 Oct 2023 09:52:40 GMT content-type: text/javascript accept-ranges: bytes vary: Accept-Encoding content-encoding: gzip server: Jetty(10.0.16) connection: close Best regards Alex
