What is a fake character checker?
Paste anything suspicious in here and it flags every character outside plain ASCII, with its code point and, for known homoglyphs, the Latin letter it impersonates. A Cyrillic а (U+0430) is pixel-identical to Latin a in most fonts, which is exactly how phishing domains and copycat usernames get built. The scan happens on the page itself, so a dodgy message never has to be sent anywhere for analysis.
How to use the Fake Character Checker
- 1 Paste the username, link or message to inspect.
- 2 Read the report of flagged characters.
- 3 Match each code point against the letter it mimics.
- 4 Copy the findings or fix the text by hand.
What you can use it for
- Spotting homoglyph spoofing in usernames or links.
- Auditing text pasted from a fancy-font generator.
- Checking that an identifier is plain ASCII.
- Reviewing suspicious messages for disguised letters.
Frequently asked questions
What exactly gets flagged?
Every code point outside plain ASCII. Recognised homoglyphs are paired with the Latin letter they imitate; combining marks and other non-ASCII characters are listed with their U+ values so nothing hides.
Where do look-alike characters show up in the wild?
Phishing domains (аpple.com spelt with a Cyrillic а), impersonation usernames, and text pasted from fancy-font generators. They render identically to the real thing in most fonts, which is the entire trick.
Does a clean result mean the text is safe?
It means every character is genuine ASCII, which rules out homoglyph spoofing. It cannot catch ASCII-native tricks like “rn” posing as “m” in a narrow font, so still read important addresses slowly.
