# fixFontAttribute(in:)

Fixes the font attribute in the specified range and assigns default fonts where appropriate.

## Declaration

```swift
func fixFontAttribute(in range: NSRange)
```

## Parameters

- `range`: The range of characters.

## Discussion

Discussion This method assigns default fonts to characters with illegal fonts for their scripts and corrects other font attribute assignments. For example, Kanji characters assigned a Latin font are reassigned an appropriate Kanji font. Raises an rangeException if any part of range lies beyond the end of the receiver’s characters.
