Font missing after the update ios 9

Hi, The indie team in service games.

After the latest update IOS 9, The fonts in the game are not visible. Exactly, comes the question box. English is also well visible. Japanese and Chinese are not visible. (It looks good on Android.) (Screenshot 1)

Google searches looked at, Unity was recently updated version. http://forum.unity3d.com/threads/unicode-symbols-and-ios-9-0.355474/

Existing Unity Version: 5.0.1 (Mac OS : 10.10.5 Yosemite, Xcode : 7.0)

I was down 5.1.3p3. Font problem was solved, The phenomenon of game forced shutdown occurred. (Screenshot 2)

If you run the same project at the 5.0.1 it does not occur. It occurs when running in 5.1.3p3.

A stuffy mind, I tested several versions.

5.0.4f1: Font error

5.1.3f1: font is half watering, forced shutdown

5.1.3p3: Force Quit

5.2.1f1: Force Quit

5.2.1p1: Force Quit

Please help .. T_T How can I solve this problem? Thank you.
