これを修正するには、データベース照合を修正する必要があります。最適かつ推奨される方法は、次のとおりです。

1. 「Jira をデータベースに接続する」内の手順に従い、必要な照合で新しいデータベースを作成します。
2. 「データベースの切り替え」に従い、古い (誤った照合を持つ) データベースから新しい適切な照合を持つデータベースに移行します。
3. If the recommended method for some reason is not suitable for your scenario, please follow this link Fixing collation manually to manually fix the collation at the database server side manually.

Supported Collations in Microsoft SQL Server

• SQL_Latin1_General_CP437_CI_AI
• Latin1_General_CI_AI

How to Verify Table Collations

SELECT DISTINCT C.collation_name 
FROM   sys.tables AS T 
       INNER JOIN sys.columns C 
               ON T.object_id = C.object_id 
WHERE  collation_name IS NOT NULL; 

How to Verify Database Collations

SELECT CONVERT (varchar(256), DATABASEPROPERTYEX('database_name','collation'));  replace the'database_name' with your Jira Database name
OR
SELECT name, collation_name
FROM sys.databases
WHERE collation_name NOT IN ('SQL_Latin1_General_CP437_CI_AI','Latin1_General_CI_AI');
