QML TextInput does not handle Korean input properly in iOS

Hello,

I am suffering to this critical bug that makes me impossible to deploy my iOS app made by Qt Quick.

Korean characters are combinatorial. For example, typing "ㅎ", "ㅏ", and "ㄴ" in a row makes the character "한".

However, in iOS, typing above elements in TextInput component shows wrong characters like this: "하ㄴ". It works well on other platforms such as Android and OSX.

Same issue was posted in Qt Forum about 4 months ago ( https://forum.qt.io/topic/61402/qt5-5-text-input-trouble-in-ios-android-is-ok ). However, it is still not fixed until current Qt version (5.6.0).
