# Charset

- `v::charset(mixed $charset)`

Validates if a string is in a specific charset.

```php
v::charset('ASCII')->validate('açúcar'); //false
v::charset('ASCII')->validate('sugar');  //true
v::charset(array('ISO-8859-1', 'EUC-JP'))->validate('日本国'); // true
```

The array format is a logic OR, not AND.
