Is Apache Tika able to learn foreign languages ​​such as Chinese, Japanese?

Can Apache Tika learn foreign languages ​​such as Chinese, Japanese?

I have the following code:

    Detector detector = new DefaultDetector();
    Parser parser = new AutoDetectParser(detector);
    InputStream stream = new ByteArrayInputStream(bytes);
    OutputStream outputstream = new ByteArrayOutputStream();
    ContentHandler textHandler = new BodyContentHandler(outputstream);
    Metadata metadata = new Metadata();
    // Set<String> langs = LanguageIdentifier.getSupportedLanguages();
    // metadata.set(Metadata.CONTENT_LANGUAGE, lang);
    // metadata.set(Metadata.FORMAT, hint);
    ParseContext context = new ParseContext();
    try {
        parser.parse(stream, textHandler, metadata, context);
        String extractedText = outputstream.toString();
        return extractedText;
    } catch (IOException e) {
        e.printStackTrace();
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (TikaException e) {
        e.printStackTrace();
    }

If the input is a document file containing Chinese characters, each Chinese character will be extracted as a “?”.

Thank you so much!

Apache Tika can extract Unicode text from supported file formats. While the file format can store Unicode text (for example, Chinese or Japanese characters), Apache Tika can extract it
