Frequently Asked Questions
What is a Unicode confusable?
A character from another Unicode block that looks visually identical to a standard ASCII character. Cyrillic 'а' (U+0430) looks like Latin 'a' (U+0061) but is a different code point.
How is this used in attacks?
Phishing sites register domains with homoglyphs (e.g., pаypal.com with Cyrillic 'а') that look identical to legitimate domains.
