Summary:
The problematic character is:
（
FULLWIDTH LEFT PARENTHESIS
Unicode: U+FF08, UTF-8: EF BC 88

[NSPredicate predicateWithFormat:@"text LIKE %@", @"*（你*"] crashes with following error:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Can't do regex matching, reason: Can't open pattern U_REGEX_MISMATCHED_PAREN (string abc, pattern *（你*, case 0, canon 0)'

I think the cause is full-width parenthesis are incorrectly treated as half-width parenthesis.

Steps to Reproduce:
1. Launch sample app.
2. Tap + button.
3. Read console logs.
