The encoded form of the IDN (including the characters for .com, .net, or .name) may contain up to 67 characters. The characters may be letters, numbers, or hyphens. A domain name may not begin or end with a hyphen. The IDN transformation software will reject a domain name if the encoded conversion exceeds the character limit.
