Loss of Encode when minimizing javascript in Grails

Question

In my javascript file there is a message with the string "service" for example. When I run the project (run-app) and check the javascript by the browser, the word appears as: "§the service". But this is displayed correctly on the screen when the message is invoked.

But when I run the system through a generated package (package), and check the javascript by the browser, the word appears as: "servi u00c3 u00a7o". When the message appears on the screen, it is displayed: "service§the"

I found a person with the same problem as mine, on that link: https://github.com/bertramdev/grails-asset-pipeline/issues/322

However the solution of using "-Dfile.encoding=UTF-8" did not work for me.

I tried with the commands below and nothing:

grails -Dfile.encoding=UTF-8 package

Gradle -Dfile.encoding=UTF-8 assetCompile

Victor this has already happened to me, is the following the encoding of the Answer of your request is different from UTF-8, which is the reason for this disorder, what you can do is to manually arrow this within the action of your controller, or you can create a Grails Interceptor and set the enconding in all your requests, I did it in my application and works perfectly, follows the code of the Interceptor.

class EncodingInterceptor {

    public EncodingInterceptor(){
        match controller: '*'
    }

    boolean before() {
        response.characterEncoding = 'UTF-8'
    }
}
