How I can convert this to READABLE text in UTF-8 format?

Solution

This is a properties file, and when it was saved to an OutputStream, any character outside of the ISO-8859-1 character set was replaced with a Unicode escape. The Properties.load(InputStream) method will decode this for you. You can then save the properties to a new file, specifying UTF-8 encoding.

static void transcodeProperties(Path src, Path dst) throws IOException {
    Properties properties = new Properties();
    try (InputStream fis = Files.newInputStream(src);
        BufferedInputStream is = new BufferedInputStream(fis)) {
        properties.load(is);
    }
    try (Writer w = Files.newBufferedWriter(dst, StandardCharsets.UTF_8, StandardOpenOption.CREATE_NEW)) {
        properties.store(w, null);
    }
}
