remove_prefix should return a new wcstring_view

[YexuanXiao]

I tried using cstring_view(str).remove_prefix to drop the first n characters of str, but since remove_prefix returns void, the call is meaningless. cstring_view should support this usage.

That doesn't make sense. remove_prefix drops them from that instance of the cstring_view. The function that does exactly what you want is substr.

remove_prefix does what it does for string, where it returns void.

I prefer remove_prefix as the name. You haven't given a good reason why remove_prefix cannot return a cstring_view. In fact, std::string does not have remove_prefix.
