# TextEncodingTypeEnum

> TextEncodingTypeEnum in the ABBYY FineReader Engine API — Output file encoding types for HTML, TXT, and CSV export.

TextEncodingTypeEnum enumeration constants are used to denote possible types of the output file encoding for export in HTML, TXT and CSV formats.

```
typedef enum {
 TET_Simple,
 TET_UTF8,
 TET_UTF16,
 TET_Auto
} TextEncodingTypeEnum;
```
