Detect deceptive Unicode characters, homoglyph attacks, and mixed scripts in any text instantly. This tool works completely in your browser and never uploads or stores your data.
The Check Spoofed Unicode Text tool helps users identify hidden or deceptive characters that visually imitate normal letters. Attackers often replace regular characters with similar-looking Unicode symbols to trick people in emails, domain names, passwords, and messages.
This tool analyzes every character locally in your browser and flags potential risks such as mixed alphabets or suspicious Unicode ranges.
Many Unicode characters look absolutely identical to regular English letters, even though they are completely different behind the scenes. A famous example is the Cyrillic letter "а", which looks exactly like the Latin "a" but has a totally different code point.
Unicode was created to support writing systems from all over the world in a single universal standard. While this solved global language compatibility problems, it also unintentionally enabled spoofing attacks using similar-looking characters from different alphabets.
Over time, cybersecurity researchers identified homoglyph attacks as a major threat vector, especially in domain names and phishing campaigns. Tools like this emerged to help everyday users quickly recognize and defend against these modern text-based exploits.
