Fix Unicode Homoglyphs (Lookalike Characters)
Detect and convert lookalike Unicode characters back to standard ASCII — free and browser-based.
Private. 100% Browser-based processing. Zero server storage.
What Is a Homoglyph?
A homoglyph is a character from a different alphabet that looks identical, or nearly identical, to a normal letter — for example, a Cyrillic 'а' that looks exactly like a Latin 'a' but is a different character underneath. These can end up in text through copy-pasting, some fonts, or occasionally through someone deliberately using them to disguise a word (a common trick in phishing links and spam). This tool scans text for characters that look like standard Latin letters but aren't, and converts them back to the real thing.
See the Difference Before & After Cleaning
Hidden artifacts and zero-width characters cause unexpected layout shifts, regex crashes, and AI detector flags. Here is how clean text compares.
Technical Character & Feature Breakdown
Our browser engine detects and strips non-printable unicode points, LLM clichés, and metadata streams automatically.
| Character / Flag Name | Identifier / Sample | Impact & Behavior |
|---|---|---|
| Cyrillic Small Letter a | U+0430 ('а') | Looks identical to Latin 'a' (U+0061) but breaks keyword searches and tricks AI detectors. |
| Cyrillic Small Letter e | U+0435 ('е') | Confusable character replacing Latin 'e' (U+0065) causing secret character watermarks. |
| Cyrillic Small Letter o | U+043E ('о') | Cyrillic look-alike for Latin 'o' (U+006F) used in homoglyph domain phishing attacks. |
| Full-Width Latin Letters | U+FF01-U+FF5E | Wide unicode symbols replacing standard ASCII characters that break database constraints. |
| Mathematical Alphanumeric Symbols | U+1D400-U+1D7FF | The fake 𝗯𝗼𝗹𝗱 / 𝘪𝘵𝘢𝘭𝘪𝘤 styled letters some AI tools and chat apps generate instead of real formatting — converted back to plain ASCII. |

Your questions, answered
Why are homoglyphs used in text?expand_more
Homoglyphs are used to bypass keyword filters, evade AI plagiarism detectors, or create look-alike phishing domain names.
Can I paste a URL to check it?expand_more
Yes — pasting a domain name is one of the more common uses, since a single swapped character is nearly impossible to spot by eye.
