Icewarp, from version 8.9 uses strict UTF encoding.
A script is provided with the Icewarp installation to convert the following data:
- Address Books
- AutoResponders
- Signatures
- Account Names
To perform the conversion please do the following:
- Locate the file convert_user_data.php.comment in directory <Icewarp>/html/admin/tools/
- Rename the file to convert_user_data.php
- Open this file using the Icewarp WebServer
e.g. http://<servername>/admin/tools/convert_user_data.php

- Select the charset of the source data from the dropdown list
- Press the Submit Query button
The script will now convert your data.
We recommend that you rename the script back to convert_user_data.php.comment after you run it for security reasons
