Domain Character Inspector
Check the exact characters in a domain name. See Unicode codes and decoded Punycode to spot lookalike letters.
Can domain names contain lookalike letters?
Yes. Distinct Unicode characters can look similar in a font. Inspecting each code point makes the underlying characters visible even when their shapes are similar.
