Jasper Reports is the default reporting tool for use with LabVantage generated reports.  We need to use a font extension to support certain special symbols (example: ≥) on the reports.  I've created a font package that packages the Arial font with the capability of using the special symbols.  

To install, follow these instructions I found online.  The font extension Jar file for Arial is attached to this solution article.  A good spot to save it to is your LabVantage project directory in Jaspersoft Studio (C:\Users\[YourUserAccountHere]\JaspersoftWorkspace\[ProjectNameHere]\bin).  An example from my system: C:\Users\sseals\JaspersoftWorkspace\LabVantage\bin
