[Q] JvYAML and non-ASCII characters

Hi,
I have questions about JvYAML 0.2.1.

Q1.
YAML.load(Reader) throws Exception when non-ASCII characters found,
but YAML.load(String) doesn't.
Why the former throws exception? I hope that YAML.load(Reader) to be
able to handle non-ASCII characters.

    /* YAML.load(Reader) throws exception */
    InputStream inputStream = new FileInputStream("example.yaml");
    Reader reader = new InputStreamReader(inputStream, "UTF-8");
    Object ydoc = YAML.load(reader);
    // Exception in thread "main" org.jvyaml.YAMLException: At 8 we
found: ### Special characters are not allowed
    // at org.jvyaml.ScannerImpl.checkPrintable(ScannerImpl.java:282)
    // ....

    /* YAML.load(String) doesn't throw exception */
    InputStream inputStream = new FileInputStream("example.yaml");
    Reader reader = new InputStreamReader(inputStream, "UTF-8");
    StringBuffer buf = new StringBuffer();
    int ch;
    while ((ch = reader.read()) >= 0)
        buf.append((char)ch);
    Object ydoc = YAML.load(buf.toString());


Q2.
YAML.dump(Object) throws exception when non-ASCII characters.
Is there any solution to handle non-ASCII characters, such as
allow_unicode=True in PyYAML?

    /* YAML.dump(String) throws exception */
    String s = "\u65e5\u672c\u8a9e";
    System.out.println(YAML.dump(s));
    // Exception in thread "main" org.jvyaml.EmitterException:
expected NodeEvent, but got #<org.jvyaml.events.StreamEndEvent>
    //         at
org.jvyaml.EmitterImpl$EmitterEnvironment.expectNode(EmitterImpl.java:580)
    //         at
org.jvyaml.EmitterImpl$EmitterEnvironment.expectDocumentRoot(EmitterImpl.java:394)
    //         ....
