You can find more info about Font Extensions here

The same problem happened to me. I tried the following way to find a solution -

If you want a font to be embedded in your Jasper Report PDF file viewer and that font is not available in your font list, all you have to do is:

• First download the .ttf file of your font you have to embed.
• After that, Go to Window -> Preferences -> Jaspersoft Studio -> Fonts. You will see a box to add your .ttf file of your font.
• Add the .ttf file of your font and tick Embed this font to PDF. After that you will see your font in the list of fonts with the name as you gave earlier.
• Select the font and export it to .jar file. And add that jar file of your font to the class path of your application if you want to view the pdf from your application.

That's it. Thank You.
