Is a domain in another script worth it?

For a local audience, what people remember is the form written in their own script. But a few things are worth settling before you commit.

Easier for local visitors No keyboard switching: the address is written the way the audience writes.
Register the ASCII form too So it can still be typed and shared on keyboards, mail clients and social platforms that do not handle the other script.
Guard the lookalikes Characters that render identically are a standard phishing tool, so register the obvious similar forms where the risk is real.
The conversion is shown The punycode actually stored in the register is displayed, so you can check it character by character before ordering.

About IDN domains

  • The registry only accepts Punycode: registering 大中華.com stores xn--fiq62dvoq.com in the registry.
  • Not every ending allows IDN registrations. Where one does not, the result shows as not checked.
  • Browsers, mail systems and DNS all handle Punycode natively, so visitors still see what you typed.

How it works

01

Enter the name

Type it as it should read, or paste a complete domain.

02

Pick the language

Registries require the language or script to be declared - zh-Hans for Simplified Chinese, for example.

03

Check the conversion

The screen shows both the Unicode and the Punycode form.

Many scripts

Chinese, Japanese, Korean, Cyrillic, Arabic and more, wherever the ending supports IDN registration.

Punycode worked out for you

Type the script; the page also shows the form actually stored in the register, so you can check it.

Language tag selector

Common tags built in, or type the standard form. ICANN requires the tag to be declared at registration.

Unsupported endings flagged

Endings marked as not taking IDN in the price list say so directly in the result instead of failing quietly.

Lookalike characters: same shape, different domain

The thing to check when registering an IDN

Different scripts contain characters that render almost identically. Attackers use them to register a domain that looks exactly like your brand and use it for phishing; the reverse also happens, where somebody registers the form you meant to take.

Before ordering, check the punycode against the string you intended. The punycode is what the registry actually stores, and one character out is a different domain. Where the risk is real, register the obvious lookalikes as well.

Mail clients and browsers

Registerable does not mean every client copes

  • Browsers, DNS and most mail systems handle punycode natively, and visitors still see the original script.
  • If you plan to send from an address in another script, test it on the clients your customers actually use before making it the main contact.
  • Not every ending allows IDN registration; where it does not, results show unconfirmed.

Why the language matters

  • ICANN requires an internationalised domain to declare the language or script it belongs to. Simplified Chinese names take zh-Hans, traditional zh-Hant, Japanese ja, and so on.
  • The registrar search command does not check the value, so a wrong or missing tag looks exactly the same while searching. It only takes effect when the registration is submitted, and a wrong one gets the registration refused.

Common questions

Should I register the ASCII form as well?

We suggest both. The script form serves your local audience; the ASCII form still works on keyboards, mail clients and social platforms that do not handle the other script.

Do simplified and traditional forms conflict?

They are different domains. Some registries treat certain variants as one registration, so register the forms you actually use before somebody else takes a lookalike.

Do IDNs cost more?

The price is the same as any other name under that ending; IDN carries no surcharge. Where an ending is expensive, that is the ending, not the script.

Why does the check still fail with a language tag?

The tag is only validated when the registration is submitted, not during the check. Failures are usually because the ending does not take IDN, or the string cannot be converted to valid punycode.

Do IDNs work for websites and mail?

Websites: yes, browsers and DNS handle punycode natively. Mail: confirm your clients accept non-ASCII addresses, and test before making it the main contact.

Why is the language required?

ICANN requires an internationalised domain to declare the language or script it belongs to. The registrar search command does not check it, so a wrong or missing tag looks identical while searching - but the registration is refused without it.

Why do some endings not support IDN?

That is each registry decision. The registrar price list states whether an ending accepts IDN registrations, and endings that do not are marked in the dropdown.

Will visitors still see the Chinese name?

Yes. Browsers and mail systems handle Punycode natively, so visitors see what you typed; the registry record holds the xn-- form.
