01
What is allowed
The base rule for domains is letters, digits and hyphens. Internationalised domain names extend that to real letters in other scripts, encoded behind the scenes in a form beginning xn--.
Decorative symbols, punctuation and emoji are not letters, so they are not eligible.
02
Emoji domains
A few small registries have allowed emoji domains, and they are widely regarded as a bad idea. Browsers often display the encoded form instead, users cannot type them, and the lookalike risk is high.
Most major registries, including .com, do not permit them at all.
- No emoji in .com, .net or .org
- Accented letters allowed on some registries
- Browsers may show the xn-- form regardless

Where a symbol is fine
Use symbols in the page title, the site name and the content. Keep the domain itself plain so people can type it from memory or read it aloud.
