Contains Special

Requires that a value contains at least one special character — any character that is not a letter or a digit.

Configuration

Config flag	Type	Description
`containsSpecial`	`boolean`	When `true`, requires at least one special character.

const form = useForm({
  initialValues: { password: '' },
  validationSchema: {
    password: { containsSpecial: true },
  },
});

import { V } from 'formify-js';

V.containsSpecial();

Scenario	Message
No special character present	`Must contain a special character`

Value	Result
`'pass!'`	✅ Valid
`'pass word'`	✅ Valid (space counts as a special character)
`'password1'`	❌ Invalid
`'123456'`	❌ Invalid

Spaces, punctuation, and symbols all count as special characters.
specialCharacters is the equivalent presence check — this rule exists so you can name the requirement explicitly alongside containsUppercase, containsLowercase, and containsNumber.
