About

Unicode contains over 149,000 characters across 161 scripts. Most messaging platforms render them faithfully, which creates an exploitable surface for text pranks. This generator applies deterministic Unicode transformations - homoglyph substitution, combining diacritical mark stacking (Zalgo), fullwidth remapping, and codepoint inversion - to produce text that looks broken, cursed, or absurd while remaining valid UTF-8. The output copies cleanly to any clipboard-compatible target. Note: rendering varies by OS and font stack. Android may drop certain combining marks above 15 per base character. Apple platforms handle Zalgo more gracefully but may collapse zero-width characters. Test on your target platform before deploying in group chats.

Formulas

Zalgo text stacks combining diacritical marks on each base character. The intensity controls how many marks are appended per character:

output_i = char_i + k∑j=1 rand(U_combining)

Where k = floor(intensity × 15) controls the number of combining marks per base character, and U_combining is a uniform random selection from three pools: above (U+0300 - U+036F), below (U+0316 - U+0349), and overlay (U+0334 - U+0338).

Upside-down transformation uses a bijective mapping f : A → A′ where each ASCII character maps to its visually rotated Unicode equivalent, then the entire string is reversed:

output = reverse(map(input, f_flip))

Vaporwave maps standard ASCII (U+0021 - U+007E) to fullwidth forms (U+FF01 - U+FF5E) with an offset of 0xFEE0:

fullwidth(c) = chr(ord(c) + 0xFEE0) if 0x21 ≤ ord(c) ≤ 0x7E

Frequently Asked Questions

Each operating system uses different font rendering engines and text shapers. Android's HarfBuzz may clip combining marks beyond a threshold (typically 10-15 marks per base character), while iOS's Core Text renderer stacks them more aggressively. Windows may display them but clip vertically in certain apps. Reduce the intensity slider if marks are being dropped on your target platform.

Most platforms preserve zero-width spaces (U+200B) and zero-width joiners (U+200D). However, Twitter/X strips some zero-width characters from tweets. Discord and WhatsApp preserve them reliably. Slack may normalize certain sequences. The invisible text mode uses U+200B which has the highest survival rate across platforms.

The mapping covers all 26 Latin letters (both cases), digits 0-9, and common punctuation. Characters outside this set (accented letters, CJK, Cyrillic) pass through unchanged since no visually inverted Unicode equivalent exists. Numbers like 2, 3, 4, 5, 7 use approximate visual matches from IPA and Latin Extended blocks.

No. The fullwidth Unicode block only mirrors ASCII codepoints 0x21 through 0x7E. Characters outside this range - including accented Latin, Cyrillic, Arabic, or CJK - are left as-is. Spaces are replaced with the ideographic space (U+3000) for consistent wide spacing.

It uses a weighted random selection from curated phrase banks organized into sentence slots (opener, verb phrase, noun phrase, qualifier). Each slot contains 20+ options. The generator tracks the last 5 selections per slot and excludes them from the current draw, ensuring no immediate repetition. With combinatorial explosion across 4 slots, the effective unique sentence count exceeds 160,000.

The output is plain Unicode text, not HTML. However, if you paste Zalgo or special characters into an HTML context without escaping, combining marks could interfere with tag parsing in edge cases. Always HTML-encode the output (replacing < > & with entities) if inserting into markup. The copy button provides raw text, which is safe for messaging but should be escaped for code.
