# TextEncodingFormat

Specify a text encoding format.

## Declaration

```occ
typedef UInt32 TextEncodingFormat;
```

## Discussion

Discussion A text encoding format specifies a way of formatting or algorithmically transforming a particular base encoding. For example, the UTF-7 format is the Unicode standard formatted for transmission through channels that can handle only 7-bit values. Other text encoding formats for Unicode include UTF-8 and 16-bit or 32-bit formats. These transformations are not viewed as different base encodings. Rather, they are different formats for representing the same base encoding. Similar to text encoding variant values, text encoding format values are specific to a particular text encoding base value or to a small set of text encoding base values. A text encoding format is defined by the TextEncodingFormat data type. The function GetTextEncodingFormat returns the text encoding format of a text encoding specification.
