Okay, so this is what fixed the issue, step by step:
1.) Add the Arial Unicode MS font extension JAR to your classpath (or any other equivalent unicode font). An "official" one can be found here, I ended up using this one, however. If you're using maven, you can use the following mvn
command line and POM entry to add the file to your classpath:
mvn install:install-file -Dfile=DynamicJasper-arial-unicode-fonts-1.0.jar -DgroupId=ar.com.fdvs -DartifactId=DynamicJasper-arial-unicode-fonts -Dversion=1.0 -Dpackaging=jar
<dependency>
<groupId>ar.com.fdvs</groupId>
<artifactId>DynamicJasper-arial-unicode-fonts</artifactId>
<version>1.0</version>
</dependency>
2.) Add, if not already present, spring-core and spring-beans to the project:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.2.2.RELEASE</version>
</dependency>
3.) Enable "Identity-H" Jasper PDF encoding:
static {
JRProperties.setProperty("net.sf.jasperreports.default.pdf.encoding", "Identity-H");
}
4.) Configure Arial Unicode MS
as your DynamicJasper font (e.g. for rows):
// ...
final DynamicReportBuilder dynamicReportBuilder = new DynamicReportBuilder();
final Style style = new Style();
style.setFont(new Font(Font.MEDIUM, "Arial Unicode MS", false));
dynamicReportBuilder.setDefaultStyles(null, null, null, style);
// ...
That was some annoying crap :-/ ...
