Unicode Confusable Checker
Paste text to find characters from different writing systems that resemble ordinary Latin letters. Mixed-script text can be accidental, but it can also make usernames, domains, filenames, and code look different from the characters they actually contain.
What the Check Looks For
The checker flags Cyrillic and Greek characters commonly mistaken for Latin letters, then shows their real Unicode values. It does not decide whether text is malicious; it simply makes mixed scripts visible so you can verify them.
