Using the Unicode confusable characters and other tricks, we can transform a text into another that looks exactly like it but remains different from a machine view.


Examples
~~~~~~~~

Replacing randomly the Latin characters by Greek or Cyrillic letters and adding the ZW(N)J.

**Original text:**

`Herman Melville (August 1, 1819 – September 28, 1891) was an American novelist, short story writer, and poet of the American Renaissance period. Among his best-known works are Moby-Dick (1851), Typee (1846), a romanticized account of his experiences in Polynesia, and Billy Budd, Sailor, a posthumously published novella. Although his reputation was not high at the time of his death, the centennial of his birth in 1919 was the starting point of a Melville revival and Moby-Dick grew to be considered one of the great American novels.`

**Srambled text with zw(n)j added (looking the same but totally different):**

**Srambled text with latin letter replaced with their Cyrillic/Greek equivalent:**

`Неrman Melvіllе (Αuguѕt 1, 1819 – Septеmber 28, 1891) wаѕ an Аmеrісаn nοvеlist, shοrt story writеr, and poеt оf the Americаn Rеnaіssanсe pеriоd.

**Srambled text with both changes:**

It is worth to notice that search engines can't find the original webpage (as free online plagiarism checkers). Searching for **Μelvillе** (with cyrillic letters) (copy-paste it) on Google doesn't return any match, though the original word **Melville** does.


Using all of the confusable characters of unicode (see the unicode confusable characters below), we can generate weird looking text worthy of old spam messages:
