Dear Friends,
I'm writing a kind of a Java module that generates Dia diagrams, but I'm
facing some problems related to the UTF-8 File format. My Java class
generates
a file but when I try to open it using Dia comes a message saying the file
format is unknown.
Altough it is in the very beginning I'm appending the java code hoping it
may help.
Thanks in advance.
