# isLogicalOrderException

A Boolean value indicating whether the scalar requires special handling
for operations involving ordering, such as sorting and searching.

```
var isLogicalOrderException: Bool { get }
```

## Discussion

This property applies to a small number of spacing vowel letters occurring
in some Southeast Asian scripts like Thai and Lao, which use a visual
order display model. Such letters are stored in text ahead of
syllable-initial consonants.

This property corresponds to the “Logical_Order_Exception” property in the
[Unicode Standard](http://www.unicode.org/versions/latest/).
