Comprehensive reference of Unicode invisible characters, zero-width code points, and homoglyphs commonly used in Unicode spoofing, phishing attacks, and text impersonation.
| Character | Type | Unicode Code Point | Effect & Risk |
|---|---|---|---|
| | Zero-Width Space (ZWSP) | U+200B | Invisible insert, splits words visually; often used in username spoofing. |
| | Zero-Width Non-Joiner (ZWNJ) | U+200C | Prevents ligatures, can hide letters; common in phishing URLs and obfuscated text. |
| | Zero-Width Joiner (ZWJ) | U+200D | Connects characters invisibly; may bypass text validation or visual inspection. |
| Medium Mathematical Space | U+205F | Invisible spacing character; used to create subtle text obfuscation. | |
| ꞁ | Latin Homoglyph | U+A7C1 | Looks like 'l', can spoof words and identifiers; common in domain homograph attacks. |
| Α | Greek Alpha | U+0391 | Looks like Latin 'A'; can spoof usernames or variable names. |
| ⅰ | Roman Numeral One (Small) | U+2170 | Visually similar to lowercase 'i'; may bypass text filters. |
| ⅼ | Roman Numeral Fifty (Small) | U+217C | Looks like 'l'; potential homoglyph risk in identifiers and URLs. |
| ０ | Fullwidth Digit Zero | U+FF10 | Looks like '0'; often used in ID spoofing or fake URLs. |
| Ｏ | Fullwidth Latin Capital O | U+FF2F | Looks like 'O'; potential homoglyph in domain phishing or identifiers. |
Detect hidden Unicode threats like zero-width spaces, , and invisible characters in your text with kovertiz.
A Unicode spoof occurs when visually similar characters, invisible characters, or zero-width spaces are used to impersonate text. kovertiz detects homoglyphs and invisible threats to prevent phishing or data corruption.
Yes. Our Unicode Unspoofer scans text for zero-width spaces, zero-width joiners, and hidden control characters that may affect string processing or security.
Absolutely. kovertiz allows you to clean or highlight imposters instantly. You can choose between auto-fix or preview mode for auditing sensitive strings.
Yes. All auditing is performed locally in your browser. No text is transmitted to any server, ensuring complete data privacy while you detect hidden characters.
All Unicode scripts are supported, including Latin, Cyrillic, Greek, and emoji. The auditor can detect cross-language homoglyphs and invisible characters regardless of the alphabet.
By identifying invisible or lookalike characters, kovertiz ensures URLs, usernames, and numeric identifiers are authentic and free from spoofing attacks.
