hello~ guys ,
is there someone who know this issue ?
i've also tried to read the "Thai" font "Waree" like below
Qt Code: 
  1. QFont font1("Waree",14,50,FALSE);
To copy to clipboard, switch view to plain text mode 
in this way, i can see the "Thai" font in my program,
but the others disappear, (Hebrew, Arabic, Traditional Chinese) all remain in blank
please help !

any reply will be appreciated!!
