How to get QML Textinput Cursor Shape as Black Rectangle

[Janardhan]

QML Textinput gets black rectangle as cursor shape when system input is keys are pressed from Keyboard by setting language to korean, and if the same keys are simulated with QKeyEvent on press of mouse click on virtually created key buttons and passing korean charaters through it, Black Rectangle cursor shape is not coming instead normal cursor is shown( so no ligature support is given in case if key stroke are simulated on mouse clicks).

Please guide how to fix this. For further details you can go through below link
