Database character set problems

ajsdhja

Because the word creation program (eudcedit.exe) is used for word creation, the GBK code point is not enough. I want to use unicode code point for word creation. However, some words created by unicode code point can be displayed in the database. Is a question mark.

  For the later parts of unicode code points (i.e. those that exceed GBK code points), the more question marks, now you want to make the database support the display of unicode code points, how to do it is to change the character set of the database

  These later code points can be displayed correctly in txt or word, which is a question mark in the database

  How to modify the character set of the database, in which step to choose the character set support during installation

To change the character set of the database, it is too simple, you only need to log in to Oracle as sys, and then: SQL> update props$ set value$='AL32UTF8' where name='NLS_CHARACTERSET';
After SQL> commit;, close it again and restart the database.

I reinstalled the server side of oracle and chose the character set'AL32UTF8', but it is still a question mark, such as the code point f8e1
I entered it manually, the question mark was displayed, and when I copied it from other places, it was displayed correctly.

I also used the zhs16gbk character set, and it is the same.

Why the character set doesn't matter

How can I solve it?
