TrueTypeFont fonts are used to write content in languages having multi-byte characters like Hindi. Content needs to be processed while being written to PDF with typographic rules like ghyph substitution according to TrueTypeFonts. OpenPDF can leverage Apache FOP for processing typographic rules. Refer #584
Add below dependencies along with OpenPDF for enabling typographic rule processing:
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>fop</artifactId>
<version>2.9</version>
</dependency>
<dependency>
<groupId>org.apache.xmlgraphics</groupId>
<artifactId>xmlgraphics-commons</artifactId>
<version>2.9</version>
</dependency>

public class HelloWorld {
public static void main(String[] args) {
