When I use oracle Jinitator to run oracle forms, I can't input uighur character, Only display ????
When I use sun jre 1.6.0.06, I can input uighur character, but not normal, some character is not model.
When I use oracle isqlplus, I can input ,search ,display uighur character.no problem. (sun jre not running)
When I run oracle forms within sun jre1.6.0.06, although uighur character not all right, but when I copy and paste to winword or notpad it is display all right.
So I think I need config sun jre1.6.0.06, but how do I ?
I use vista, microsoft uighur.ttf.
uighur is a arabic text.
