There were issues with Grouper and international characters.  In this case it had nothing to do with the grouper code, but rather the database settings, connect string, file encoding, and java startup parameters. 


In Grouper 2.2.1 patch grouper_v2_2_1_api_patch_9 there are checks at startup to check for non English character handling, database transactions, and database case sensitivity..


There are checks at startup to make sure the non tomcat settings are correct, also the default for for file encoding was changed. If you dont need non english chars and you are worried about the risk of this change please change it in


# when reading writing files from util classes, this is encoding (was ISO-8859-1)

grouper.default.fileEncoding = UTF-8

These settings will detect if you database and file system can handle utf-8, and if transactions, and case sensitivity are handled correctly. You can get a success message if you are debugging, but this defaults to off. These will run in another thread so they dont affect start time (optionally default to true)


# if should check database and utf in new thread

configuration.checkDatabaseAndUtf.inNewThread = true


# if grouper should check to see if the database has case sensitive selects

configuration.detect.db.caseSensitive.problems = true

configuration.display.db.caseSensitive.success.message = false


# if grouper should check to see if utf-8 works on startup in files

configuration.detect.utf8.file.problems = true


# if grouper should check to see if utf-8 works on startup in the database

configuration.detect.utf8.problems = true

configuration.display.utf8.success.message = false


# if grouper in the utf8 check will check to see if grouper supports transaction

configuration.detect.db.transaction.problems = true

configuration.display.transaction.success.message = false

If there is a problem with start, you will see a message like this, but it will not cause grouper not to start:


Error: Cannot properly read UTF string from database: '???????', make sure your database has UTF tables and perhaps a hibernate.connection.url in


Note, it will try to give suggestions about what the problem could be.

Following up on your suggestion to try out GRP-1128 with the installer, I am not seeing anything different from master. Just ran a 2.2.1 install and tried to create a group as میثاق


Attached is what I see.
