Finally, `options` can contain the keys `gt` and/or `lt` which will enforce integers being greater than or less than, respectively, the value provided (e.g. `{gt: 1, lt: 4}` for a number between 1 and 4).

**isMultibyte(str)** | check if the string contains one or more multibyte chars.

**isNumeric(str [, options])** | check if the string contains only numbers.<br/><br/>`options` is an object which defaults to `{no_symbols: false}` it also has locale as an option.

**isRFC3339(str)** | check if the string is a valid [RFC 3339](https://tools.ietf.org/html/rfc3339) date.
