After importing from Trac into any database, special characters such as umlauts are not imported properly in certain fields.


Diagnostic Steps

  • All of your table and database collations are utf-8.
  • Import from Trac.
  • See "?" instead of your special character in some fields but not others.


  1. As per Setting properties and options on startup, add the -Dfile.encoding tag and set it to utf-8.
  2. Restart JIRA.
  3. Reimport your data.
