Strange encoding after production build of SAPUI5 app

Hello,

We are currently facing a problem with the WebIDE deployment process to our own SAPUI5 ABAP Repository.

We have a prepared an i18n.properties file, where all the German strings are saved.

If we start the application on the WebIDE itself, then the encoding of the strings works perfectly as expected. But when we are now trying to build and deploy the app on the ABAP repository, it will fail with the encoding. During the build process on the WebIDE, it convert the the i18n properties file in another encoding. We see the file here from the dist folder.

As a result, we see a wrong encoded application:

Now the question is, what can we do to set the correct charset and get the expected result.

Thanks in advance.
