OK. I thik thik it was the conersion to utf-8 that was misssing. Not clear here
that the input byte array is supposed to be a UTF-i multibyte char. The
argument probably should be String but at least we know now that is the input
rather than just a byte representing a dot pattern. We should update the
comments and documentation to make that clearer. We should implment the class
in BrailleBlaser to take the simple arguments byte (representing braille dots
and String representing UTF-8 and do the onversion there gefore callin he JNI
interface call.
