--- Comment #27 from Michal Suchanek hramrach@centrum.cz 2009-05-09 15:16:53 --- Yes, it seems to work.
However, I would like to confirm with something other that this test application, preferably something that can generate some output that can be verified as properly encoded.
Also the ability to input Japanese characters into the test application in English locale is somewhat odd.
