Special Characters are Replaced with a Square in Editor
Problem
My file was created with other application and it contains special characters (such as é, ©, ®, etc.) Why does Oxygen XML Author plugin display a square for these characters when I open the file in Oxygen XML Author plugin?
Solution
You must set a font able to render the special characters in the Font preferences. If it is a
               text file you must set also the encoding used for non
                  XML files. If you want to set a font that is installed on your computer but that
               font is not accessible in the Font preferences that means the Java
               virtual machine is not able to load the system fonts, probably because it is not a
               True Type
               font. It is a problem of the Java virtual machine and a possible solution is to copy
               the
               font file in the [JVM_DIR]/lib/fonts folder.
               [JVM_DIR] is the value of the property java.home that is
               available in the System properties tab of the
               About dialog box that is opened from menu .
