Homoglyph Check

Detects Unicode lookalike characters that impersonate ASCII Latin letters, a common phishing-domain trick.

Overview

Detects Unicode lookalike characters that impersonate ASCII Latin letters, a common phishing-domain trick. Scans text (typically a domain, email, or username) for Cyrillic / Greek / fullwidth / mathematical lookalikes plus zero-width and RTL-override / bidi-control characters. Returns per-character findings (codepoint, block, impersonates), block counts, mixed-script flag, ASCII-folded normalized form, and a 0-100 risk score with bucket. Use it as a homoglyph detector, Unicode lookalike scanner, IDN spoof check, phishing-domain inspector, typosquat detector, mixed-script analyzer, or zero-width-char finder.
