This is especially useful if your SQL is color-coded with the same conventions as it was in your IDE. It is even better still if your browser can allow you to scan through many files, moving from file to file with a single click.

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?
