Jaspersoft Localization Reference

JasperReports Server supports the full Unicode character set using UTF-8 encoding. It also depends on the underlying database and application server to support the UTF-8 character encoding. If you use the bundled Tomcat and PostgreSQL software, UTF-8 is configured by default. If you use any other software, refer to the JasperReports Server Administrator Guide for instructions about configuring software to support UTF-8.
