Unicode Domain Warning
Description from store

Displays a warning page for domains with Unicode characters, to avoid potential "homograph" attacks or look-alike domains.

Features:
✓ Displays and highlights the unicode characters
✓ Displays the ASCII "Punycode" version of the domain name
✓ Whitelist a website so it never shows the warning again
✓ Option to ignore certain unicode characters you specify
✓ Works on TLDs and subdomains

How To Use:
• If a warning is displayed, you can click a button to whitelist the domain, dismiss it for the current session, or go back.
• To remove an existing whitelisted domain, right click the extension icon in the toolbar, then click "Options" / "Extension Options".
• You can also set specific unicode characters that should be ignored in the same options menu.

Privacy Notes:
• No tracking, analytics, or usage data collection of any kind.
• No External Requests: The extension runs entirely offline on your device; no data is ever sent to external servers.
• Only your whitelisted domains and characters are stored in your browser's synced settings.

This extension is designed to enhance security by: * Displaying a warning when visiting domains with Unicode characters. * Showing the non-Unicode "Punycode" version of the domain to help avoid "homograph" attacks or look-alike domains. * Allowing you to whitelist secure sites so the banner doesn't appear. * Running entirely offline, with no data sent to external servers. * Only storing whitelisted domains and page titles in your browser's synced settings.

Perfect app to fix a security flaw in chrome. this helps with international keyboard characters used in website name creations. this app helps make sure you are going to the correct website. note you still go to the website, it just gives you the information to know that if it's fake you don't enter in your critical credentials or other information.

I spend a lot of time in international chat rooms, often being sent to obscure sites to view content pertinent to the conversations. I can't just click away and hope for the best, but must instead take all due diligence to insure the landing zones are not dangerous. This is a safe and simple tool for me to use in that effort. Thanks!
