The method Character.isLetterOrDigit() does not match the spec.

The spec says that \u1FFF and \u3040 will return true as being either a char or a digit. The current code returns false.

Here is a test case to reproduce the bug
to run put /net/castor.east/jtg/testbase/src/modena_jlib2_2/classes in your classpath

The unicode chars \uFDFF and \uFEFE are also incorrect.

Here is a test case for them
