Display symbol characters in Linux?
I am running Mustang build 98 on Ubuntu Linux, and something weird is happening in three different Java apps when I want to display characters that are outside the Latin-1 range (such as a Greek Delta ?).
In NetBeans, JEdit, and XMLMind, I can paste a ? into any text field, and it shows up fine. But inside a styled text area, I get the  rectangle for a non-displayable character.
The XMLMind support told me that this works fine on Windows and I should go pound sand.
I looked at jre/lib/fonts.properties, and I couldn't see any special mapping for these symbols. At any rate, I have no explanation why they work in some parts of a Java program and not in others.
Could you help me out? I need to edit some math in XMLMind, and it is very frustrating to look at  =  + .
