Clean up text · homoglyphsCyrillic letters in English text
A word looks English, but a Cyrillic “а” or “о” is hiding inside — and search, spell-check and string comparison no longer recognise it. We find such words and fix them.

About homoglyphs
More than a dozen letters look the same in the Latin and Cyrillic alphabets. Mixed words appear when copying from PDFs, when typing with the wrong keyboard layout, and on purpose — to slip past filters or fake a brand name. We check every word: if it has letters from both alphabets, we highlight them and offer to replace them with letters of the alphabet that dominates the word.
Lookalikes
18 pairsa а · o о · c с
Lowercase a, e, o, p, c, y, x and uppercase A, B, E, K, M, H, O, P, C, T, X match Cyrillic letters by shape.
Why it matters
Search0 matches
The word “table” with a Cyrillic “а” is found neither by site search, nor by Ctrl+F, nor by a database query.
Where they come from
PDF and layoutPаssword
Most often from copying out of PDFs and typing with the wrong layout. Less often — on purpose, in phishing.
Filters
Bypasswill not work
Spam filters and plagiarism checkers map lookalikes to one alphabet before comparing, and flag many of them as suspicious.
How we fix
By majorityPаssword → Password
If a word has more Latin letters, the Cyrillic lookalikes become Latin, and the other way round.
Standard
UTS #39confusables
Lookalike characters are described in the Unicode security standard — browsers use it to defend against fake domains.
