# AVCaption.TextCombine

The caption’s supported rendering policy options.

## Declaration

```swift
enum TextCombine
```

## Overview

Overview Text combine is a special rendering policy that combines multiple characters into one unit and presents it in upright position in a vertical text flow. This presentation achieves a horizontal-in-vertical layout (or Tate-Chu-Yoko layout), which lets the caption render a horizontal text string in vertical text.
