How to enable international keyboard support in Apportable?

问题

Currently, I am trying Apportable starter kit. And UITextField doesn't seem to work properly with non-English keyboard. I want to know how to enable the non-English keyboard.

Android OS (4.x) in the device(Samsung Galaxy S2) is running in Korean language mode, and also Korean keyboard is installed and enabled in system settings app. The keyboard is working well in other apps. But in apps built by Apportable, it doesn't work. After I changed language mode to Korean, it still input English character instead of Korean character composition.

Here's what happening when I press ㅎ key. g is placed instead of ㅎ character. In English keyboard, g was at the same position where the ㅎ key is.

Update

I investigated this further, and discovered these points.

Test results with some devices.
- Samsung Galaxy Gio (factory default Gingerbread) : Works well. No issue.
- Samsung Galaxy S Hoppin (factory default Gingerbread) : Works well. No issue.
- Samsung Galaxy S2 HD LTE (updated to Jelly Bean, 4.1.2) : Doesn't work. Same issue.
- Samsung Galaxy S2 (updated to Jelly Bean 4.1.2) : Doesn't work. Same issue.

I couldn't test with recent devices because I don't have one.

This issue happens only in qwerty mode of the same keyboard software. Another input modes of the same keyboard software works well.
Google qwerty keyboard app installed from Android Market works well.

I think this is a bug of Samsung software only for specific version...

Reproduction

Here's full source code for AppDelegate.m file to reproduce this issue. Just create a new project, copy and paste. Then you will see the problem. Your Android OS need to be set to Korean mode and also Korean keyboard need to be enabled. I think this can be tested with another language keyboard like Japanese or Chinese which needs dynamic composition.
