Did you encounter any problems using NLTUI to do the translation? I know Chinese is treated a little differently from all the latin languages internally, so I suspect you may have come across a bug or the other.
I see EasyBCD has problems showing the text in some places:
I'll look into that. It's not a problem with your translation, though.
BTW, I think EasyBCD looks beautiful with the Chinese text. It's so pretty!
