# kUCCollatePunctuationSignificantMask

## Declaration

```swift
var kUCCollatePunctuationSignificantMask: Int { get }
```

## Discussion

Discussion If the corresponding bit is set, then punctuation and symbols are treated as significant instead of ignorable. This will produce results closer to the behavior of the older non-Unicode Mac OS collation functions. This option is available with Mac OS 9 and later.
