Fixing the Error

On SQL Server 2025, I have a database that has this collation: SQL_Latin1_General_CP1_CI_AS. I decide I want to run this code:

SELECT UNISTR('*3041*308A*304C*3068 and good night', '*') AS 'A Classic';
I get this error:Msg 9844, Level 16, State 4, Line 24 The char/varchar input type uses an unsupported collation. Only a UTF8 collation is supported with char/varchar input type in UNISTR function.What is the easiest way to fix this error?
