JFormDesigner doesn't display some languages properly, see attached screen shot, particularly Russian and Hebrew. The only reason Chinese is shown ok is because I've converted it into ASCII. All files are encoded in UTF8 but JFormDesigner seems to ignore that, I've tried to enforce -Dfile.encoding=utf-8 property in JFormDesigner.vmoptions file, but to no avail.. Tried in several versions including the latest one, the support is no reachable. Stuck!
Anybody seen this problem?

I had this problem too . the result is you make some change in your initComponents() (for labels or buttons or other element at defining)
1- put all the text you want to show in your UI at a resource bundle (you can make it when you want to create a new jformdesigner form , at localization , check the store string in resource...
2- find the element that you want to have UTF-8 text for example i want to make a lable with UTF-8 text
then get the string
now change it to UTF-8
be careful that you need a try()/catch block
any other strings can be set with this method
