I believe the Unicode version supported on Symbian/Nokia devices are 3.? something, and it is too old for me. It causing problem's when I trying to display some Uyghur language on mobile. All the other problem has solution but just one simple Unicode redirection of Uyghur character 0x0647 explained in detail in following thread.
I actually more than 10 million Uyghur eagerly waiting for Nokia do something with their supported Unicode version, I am wondering when it is going to happen?
