MySQL query shows something like 0x8081 instead of special characters

When i run SELECT CHAR(128,129,130,131,132,133,134,135,136,137);

I got 0x80818283848586878889 istead of Çüéâäàåçêë.

Does anybody know why?

I’m using charset utf8mb4.

When I run show variables like '%char%'; I got

+--------------------------------------+--------------------------------+

The output charset is “DOS West European”

Use this query it will display the text in charset “DOS West European”

SELECT CHAR(128,129,130,131,132,133,134,135,136,137 using cp850)
