Please try to substitute your fonts jar with this one:
http://pd4ml.com/i/allfonts.zip (34 MB!)

unpack it and place fonts.jar to the classpath of your application (or to lib/ folder if any).
Refer the fonts this way:
pd4ml.useTTF(“java:fonts”, true);

And make sure the HTML has a correct meta charset directive.

Does it solve the problem?
