# NSGlyphInfo

A glyph attribute in an attributed string.

## Declaration

```swift
class NSGlyphInfo
```

## Overview

Overview Glyphs are the graphic representations of characters, stored in a font, that the text system draws on a display or printed page. Before text can be laid out, the layout manager (<NSLayoutManager) generates a stream of glyphs, using the character and font information specified by the attributed string and contained in the font file. NSGlyphInfo represents a glyph attribute value (NSGlyphInfoAttributeName) in an attributed string (NSAttributedString) and provides a means to override the standard glyph generation process and substitute a specified glyph over the attribute’s range. Glyph attributes are integer values that the layout manager uses to denote special handling for particular glyphs during rendering. NSGlyphInfo enables you to override a font’s built-in mapping from a Unicode character code to a corresponding glyph ID. Overriding the mapping allows you to specify a variant glyph for a given character if the font contains multiple variations for that character or to specify a glyph that doesn’t have a standard mapping (such as some ligature glyphs).
