Problem
Non-English characters are displayed as question marks.
Solution
This can be caused by the Java Virtual Machine (JVM) that Jira runs on not having the correct encoding set. Configuring Jira to start with UTF-8 set as its default encoding can fix this problem.
Add the following as Jira startup parameters:
-Dfile.encoding=utf-8
-Dsun.jnu.encoding=UTF-8
