When I used the camunda-modeler tool, I found a zh-CN.pak file. I wonder if it can be set to Chinese?
This file has nothing to do with internationalization of the Camunda Modeler. As of now it is only available in English. However, it is possible to translate parts of the modeler using the built-in i18n capabilities. Here’s an example. Finally, you can use a Camunda Modeler plugin to add your translation.
