# `GSGlyph setUnicodesFast:`

*Instance Method*

Assigns Unicode code points without updating related state.

## Declaration

```swift
func setUnicodesFast(_ unicodes: NSOrderedSet?)
```

```objc
- (void) setUnicodesFast:(NSOrderedSet *) unicodes;
```

```python
setUnicodesFast_(unicodes: NSOrderedSet)
```

## Parameters

- `unicodes` — The Unicode code points as hexadecimal strings.

## Discussion

This method does not register undo or update glyph lookup in the containing font. The caller is responsible for supplying valid Unicode code point strings. Use [`GSGlyph.unicodes`](/Core/GlyphsCore/GSGlyph/unicodes) for general assignment.
