How to express an unicode code points set in match command?

Question

My test.txt for this example.

　  unicode 3000  (whitespace in Chinese mark)
！  unicode ff01
＾  unicode ff3e
～  unicode ff5e 

The command can match whitespace in Chinese mark(u3000).

hi! ChineseMark ctermbg=red guibg=red
match ChineseMark /\%u3000/

And ！ can be matched with

match ChineseMark /\%uff01/

And ＾ can be matched with

match ChineseMark /\%uff3e/

And ！ can be matched with

match ChineseMark /\%uff5e/

Now i want to match character whose unicode code point is u3000 and characters whose unicode code points are from uff01 till uff5e.

match ChineseMark /[\%u3000\%uff01-\$uff5e]/

The expression /[\%u3000\%uff01-\$uff5e]/ can't do the trick,How to express this kind of unicode code points set in match command?

Answer 1

The syntax for unicode characters inside [] is different, you just omit the %:

match ChineseMark /[\u3000\uff01-\uff5e]/

\%uxxxx is an atom while \uff01 is character in a collection. You cannot use atoms inside collections. See :help /[.
