Ghost App “KEYBOARD DATA” (Chinese &Japanese) it was on my IPhone 4 and every model since. If it is part of a necessary file, what is it doing here. ?

why don’t they have Romanian or Bulgarian, why just Chinese and Japanese!

Chinese and Japanese use ideograms to represent words instead of strings of letters like most other languages. As a result, the system used to input them with a keyboard is different, and essentially uses a database to translate the letters you type into individual Han characters, of which there could be several different ones depending on the context. That's the kind of data which is involved in what you are seeing.
