Issue: [iOS] The styling does not change when the CJK character enter TextInput
Labels: Platform: iOS,Issue: Author Provided Repro,Component: TextInput,Needs: Triage :mag:,Newer Patch Available

### Description

When entering CJK characters in the TextInput component, the styling does not change.

I wanted to change the styling according to the type of characters entered, but I don't think react can detect the state change.

The example screen is,
The even number of letters is red
The odd-numbered letter is a simple logic that handles it in blue.

Logic does not work in Korean while it works normally in the English environment.
From searching, it seems that this phenomenon occurs in Korean, Chinese, and Japanese equally.
