Usually, this is a problem with the installation of Confluence or Graphviz.

1. Check your graphviz installation.

   1. Create a file test.dot with the following content:

      Code Block
      digraph test { state [label="insert characters that are not shown correctly"] }

   2. Let graphviz create a the image. Do this as user who runs Confluence and use the same Graphviz version as Confluence. You can check this as described in PlantUML Version Information.

      Code Block
      dot -Tpng test.dot -otest.png

   3. Check the created test.png. If the image is correct check Confluence. If not, you have to correct your Graphviz installatoin.
2. Verify that all parts of your Confluence installation use the correct encoding which should be UTF-8.
   
   • Tomcat connector in conf/server.xml: URIEncoding="UTF-8"
   • Java command line argument: -Dfile.encoding=UTF-8
