# NSControlCharacterZeroAdvancementAction

An action that removes the glyph from layout.

```
var NSControlCharacterZeroAdvancementAction: Int { get }
```

## Discussion

Glyphs with this action are filtered out from layout ([`notShownAttribute(forGlyphAt:)`](/documentation/UIKit/NSLayoutManager/notShownAttribute(forGlyphAt:)) `== YES` for the glyph).
