Description of problem:
When an alert template is applied to a message containing Russian characters (which are properly shown in the JBoss ON UI), they will be replaced in the received email with the "?" characters.

Version-Release number of selected component (if applicable):
3.3 (reproduced with 3.3.0 and 3.3.10)

How reproducible:
Always

Steps to Reproduce:
1. A resource is configured to collect events where some of the collected messages contain Russian characters - for an example - see attached log file;
2. Create an alert that is triggered when Event - INFO is collected and choose email as a notification;
3. Copy the message from the provided log file and add it as a new message to the same log file;
4. Save the change and execute "sync" on the terminal;
5. Navigate to the JBoss ON UI and confirm that newly added message is shown in the list of Events;
6. Navigate to the alert history page for the same resource and confirm that new alert has been triggered;
7. Check the Inbox for the new email from the JBoss ON

Actual results:
Newly received email will contain "?" characters;

Expected results:
Newly received email contains Russian characters as shown in the JBoss ON UI;


Additional info:
When the same message is sent from the JBoss ON UI Test Email page (http://<jon_server_ip_address>:7080/coregui/#Test/ServerAccess/EmailTest) received email is correct (no "?" characters). Unfortunately, we cannot use "Use Alert Template" check box for this as the template will be applied to the default text:
