Android does not support these characters. http://code.google.com/p/android/issues/detail?id=26037
Problem is fixed in Android 4.3
Copy fonts from android 4.3 release and use as custom font in application to support old android devices.
TextView tv = (TextView) findViewById(R.id.test);
Typeface typeface = Typeface.createFromAsset(getAssets(), "custom.ttf");
tv.setTypeface(typeface);
