a bug about double-width CJK character display

[codehz]

If it is fixed-width, it will incorrectly wrap (which line containing CJK characters), or it will be longer than under normal line. I think that it should take two characters, or cutting trailing spaces. There are many programs can output these characters correctly, such as clang, it requires a terminal with an appropriate font (the width of the CJK characters exactly twice the general character width font)

I think it can be corrent position,but this line longer than others
