For a full set of ASCII characters, use {{$string.sample}}. For a custom set of characters, use {{$string.fromCharacters}}.
For strings of base-ten digits, use {{$string.numeric}}. For other bases, use {{$string.binary}}, {{$string.octal}}, or {{$string.hexadecimal}}).
You can generate standard ID strings using {{$string.uuid}} or {{$string.nanoid}}.
