The Java versions were pre-Qt, if I'm remembering correctly.  The were 
left in for the case where the GUI is not built, something I've been 
configuring because of compilation bugs on my slightly outdated system. 
 (I don't use the dialog boxes at the moment, though.)  After the Java 
fallback is a terminal window dialog simulation, I think.

By TeX symbols I'm guessing it's meant just the Greek and math 
characters.  I think Qt accepts unicode, so one should be able to copy 
these symbols from any relevant table (e.g., search for a Greek alphabet 
on the web) then copy those into the character string used for the 
dialog box message inputs, in theory anyway.
