By default, ls will print ? in place of non-printable characters,
according to your current locale's definition of printable characters.
Either change your locale to something that prints those Chinese
characters, or look into using the --show-control-chars and
- --quoting-style options of ls to force these characters to print.

That is because more does not worry about what non-printing characters can
do to a terminal, but just blindly prints them; fortunately, your terminal
displays them sanely.

No, it is other programs that have a weakness in that they will blindly
print non-printing characters to a terminal, even if doing so will corrupt
the terminal display.
