c++ but with the java wrappers I get <span class=GramE>a</span> “Error
reading binary data” in reader.<span style='mso-spacerun:yes'>
</span>Also, I have tried to use the writer to write out ASCII to a string and
noticed that is not supported as it gives <span class=GramE>a</span> “<span

below). The image comes out on the other side corrupted.<span
style='mso-spacerun:yes'> </span>There is something definitely wrong with the
bytes or the interpretation of them, possible due to the JNI layer or due to
the fact that the <span class=SpellE><span class=GramE>RegisterAndGetOutputString</span></span><span
class=GramE>(</span>) is returning a Java String and not a char[];<span
