System error occurs , with japanese annotation.

Dear Developers.

I'm a user of "Adobe Reader for Android" in Japan. (This content is translated from Japanese.)

When I open any PDF file with Adobe Reader for Android and put annotation comment in japanese,  "System error" occurs.

Here is my steps.

1. Open arbitrary pdf file with Adobe Reader for Android.

2. Tap the pencil icon.

3. Tap the "T" mark icon.

4. Tap any point int the view and input dialog box opens.

5. Input any comment in japanese and tap "Save" button.

6. Then "System Error" toast occurs and there isn't saved comment in the view.

OS：Android 5.0.1

Adobe Reader 11.7.1

I would glad if you fix this issue.

Thank you.
