# toBeWide

::: warning Deprecated
Prefer [toHaveAttrs](/matchers/to-have-attrs) which checks multiple attributes at once:

```typescript
expect(term.cell(0, 0)).toHaveAttrs({ wide: true })
```

:::

Assert that a cell contains a double-width (wide) character, such as CJK characters or certain emoji.

## Signature

```typescript
expect(cell).toBeWide()
```

## Usage

```typescript
// CJK character occupies two columns
expect(term.cell(0, 0)).toBeWide()

// ASCII characters are not wide
expect(term.cell(0, 0)).not.toBeWide()
```

## Accepts

| Region            | Supported |
| ----------------- | --------- |
| `term.cell(r, c)` | Yes       |
| `term.screen`     | No        |
| `term.row(n)`     | No        |

## Notes

* Wide characters occupy two terminal columns
* The first cell of a wide character has `toBeWide()` true; the second cell is a continuation cell
* Common wide characters: CJK ideographs, fullwidth forms, some emoji
