检查符号（✓）不使用jasper报告以PDF格式显示

Question

I developed a report in jasper wherein it displays a check symbol(✓) for existing records (ie list of requirements). It seems like I would never had a problem displaying it since the check symbol is visible during preview in the iReport. But once I viewed the report in PDF format, the check symbol is no longer visible. I even tried unicode characters instead of the check image, even unicode for square root.

What configuration am I missing here?

To passing value to this variable as

String imagePath = FacesContext.getCurrentInstance().getExternalContext().getRealPath("/images/IMAGE.jpg");

Then put parameters as given below

paramaters.put("paramImage",imagePath);
