Description

Unable to input the Chinese words to the UITextField. A Chinese word can be represented by one to four symbols in Zhuyin.

For example：ㄊㄞˊ => 台

2. Type ㄊㄞ and no words will be suggested.

Hey @AnandRaj32! Thanks for this! I see what is happening, but I found that whenever I unhook your event handler Handle_ShouldChangeCharacters the suggestions work just fine. So it looks like something is happening in your code in the event handler that triggers this? Is that something you are seeing as well?

@jfversluis Thanks for the update!
I have already told that If we return true in ShouldCharacterChanged event the keyboard suggested properly. If I have returned false only the keyboard not shown properly.

We have handled the text in our side, so only we returned false in ShouldCharacter changed event. Please let me know if you need any other details.
