When entering Chinese text, a standard Latin keyboard and autocorrect is used. Text entered in Latin letters is replaced with a Chinese alphabet equivalent. For example, 'yang' will be replaced with '杨'. However, in iOS, the char limit prevents entering a longer Latin alphabet equivalent.

Steps:
1. In iOS device add Chinese Keyboard: Settings > General > Keyboard > Keyboards > Add New Keyboard... > Chinese (Simplified) - Pinyin
2. Build and Run attached project ("Input field.zip") for iOS
3. In Player: click on Text Box
4. Switch to Chinese keyboard
5. Enter 'yang ' (with space) 7 times. Notice: after clicking space, 'yang' is converted to '杨'

Expected: it is possible to enter '杨' 7 times as the char limit is set to 7.
Actual: after entering 4 times, 5th time the user is prevented for entering 'yang', as a result, autocorrect doesn't work and it can't be replaced with '杨'.
