# UCKeyStateTerminators

Lists the default terminators for each dead-key state handled by a 'uchr' resource.

## Declaration

```swift
struct UCKeyStateTerminators
```

## Overview

Overview The Unicode keyboard-layout ( 'uchr') resource contains the data necessary to map virtual key codes to Unicode character codes for a given keyboard layout. The 'uchr' format consists of a header information section and five key mapping data sections. The UCKeyStateTerminators type is used in the fourth key mapping section of the 'uchr  ' resource.  The UCKeyStateTerminators structure contains the list of default terminators (characters or sequences) for each dead-key state that is handled by a 'uchr' resource. When a dead-key state is in effect but a modifier-and-key combination is typed which has no special handling for that state, the default terminator for the state is output before the modifier-and-key combination is processed. If this table is not present or does not extend far enough to have a terminator for the state, nothing is output when the state terminates.
