Same appearance does not mean same text

Fonts can make characters from different scripts look identical or merely similar. Search, equality checks, domains, and source code still treat their code points as different.

Cyrillic and Latin look-alikes

The table focuses on common Cyrillic letters that can resemble basic Latin in typical interface fonts. Exact similarity depends on the font and style.

Identifiers and domains

Treat unexpected script mixing as a signal

Compare code points

Visual comparison is not enough. Inspect Unicode values or script properties when a domain, login, filename, or identifier is suspicious.

Restrict identifier scripts

For security-sensitive identifiers, prefer one expected script and flag unexpected Cyrillic–Latin mixing.

Do not auto-replace prose

Legitimate multilingual text can mix scripts. Automatic replacement may corrupt names, quotations, formulas, or source code.

Important limitation

This compact table is a human reference, not a complete spoof detector. Unicode confusable data includes many scripts, multi-character mappings, normalization, and font-dependent cases; production checks should implement UTS #39 or a maintained library.

Unicode

Specification and data

Unicode Technical Standard #39 defines confusable detection and mixed-script checks. Its machine-readable confusables file is versioned and can evolve, so security tooling should track a specific Unicode release.
