IBM Watson Assistant - 变音符号

Question

Recently, I tried to work with IBM's Watson text assistant. I chose to program it with Java and everything worked alright until I tried to use German phrases, which use umlauts [ä, ö, ü].

The skill language is also German.

When receiving a response from the API, all umlauts where replaced by �.

Here's the code:

public String inquiry(String anfrage){
    MessageInput input = new MessageInput();
    input.setText(anfrage);

    MessageOptions options = new MessageOptions.Builder(WORKSPACEID)
            .input(input)
            .build();

    MessageResponse response = assistant.message(options)
            .execute()
            .getResult();

    return response.getOutput().getGeneric().get(0).text();
}

Do you know a way to properly get umlauts from the IBM API?

Answer 1

This line did it in my case. (Thanks to @data_henrik)

System.setOut(new PrintStream(new FileOutputStream(FileDescriptor.out), true, "UTF-8"));
