thanks for your checking and your research results.
It took some time until I have seen the difference ;-)

Edit:
@HP / @ Tim:
In my virtual calculator there are always the chinese characters

Do a shift home(icon) and go to the second page. there is a Textbook Display , uncheck the box(make it blank). Joe Horn mentioned a few times that Textbook Display and CAS sometimes cause strange results.
