[bbskill]

hello all,

I compiled my application based SWT into linux native code using gcj4.1.
My application use saxParser to
parse a xml file which its enconding is UTF-8 and display the content on
the SWT Control.
the xml file contains some Chinese characters.
when I run my natived application , the Chinese Characters can't be
identified , and other English Charactors
work well . but it works all well in JVM.
can I solve it ??
Thanks for your any help .
