About Unicode Text Spoofing

Unicode text spoofing replaces regular Latin characters with visually similar characters (homoglyphs) from other alphabets such as Cyrillic, Greek, or other Unicode scripts. These characters look identical to the human eye but have different Unicode code points.

This technique can be used for various purposes including testing security systems, bypassing text filters, or educational demonstrations of Unicode security issues. The tool includes options for zero-width spaces, punctuation spoofing, and preview mode. If you need to do the opposite—clean up text that contains hidden Unicode characters or markers—try our Remove AI Markers from Text tool.

Frequently Asked Questions (FAQ)

What is Unicode text spoofing?
Unicode text spoofing replaces regular Latin characters with visually similar characters from other alphabets like Cyrillic or Greek. These characters look identical but have different Unicode code points.
What are the different spoofing methods?
There are four methods: Homoglyphs (replace with similar characters), Invisible Chars (insert zero-width spaces), RTL Override (use right-to-left text direction), and Combined (uses multiple techniques).
What are homoglyphs?
Homoglyphs are characters that appear identical or very similar but have different meanings or come from different scripts. For example, Latin "a" and Cyrillic "а" look the same but are different Unicode characters.
What are zero-width spaces and invisible characters?
Zero-width spaces and other invisible characters are Unicode characters that take up no visual space but are still present in the text. They include zero-width space, zero-width joiner, soft hyphen, and others.
What is RTL Override spoofing?
RTL Override uses Unicode bidirectional control characters to change text direction, which can make text appear differently than its actual character order. This can be used to create deceptive text displays.
What does the intensity slider do?
The intensity slider controls what percentage of characters get replaced with homoglyphs. Lower intensity replaces fewer characters, while higher intensity replaces more.
What is preview mode?
Preview mode shows the differences between original and spoofed text by displaying replacements as [original→spoofed] and invisible characters as [INV]. This helps you understand what changes were made.
Is my data processed securely?
Yes, all text processing happens entirely in your browser. No data is sent to any server, ensuring complete privacy and security.
What can this tool be used for?
This tool can be used for testing security systems, bypassing text filters, creating unique text variations, or educational purposes to understand Unicode security issues.
How can I verify if text has been spoofed?
You can detect spoofed text by generating a hash of the original and comparing it to the spoofed version. Use our Hash Generator to create MD5 or SHA hashes—even visually identical text will produce completely different hashes if Unicode spoofing was applied.
