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. Amоng his bеst-known works arе Μoby-Dісk (1851), Τyреe (1846), a rоmаnticizеd accоunt оf hіs eхрerіencеs in Ρоlynеѕiа, аnd Вilly Budd, Ѕаіlοr, а pοsthumously рublіshed nоvеllа. Although hiѕ reputation was nοt hіgh at thе tіme οf hіѕ dеаth, the сentennіаl оf hіs bіrth in 1919 waѕ thе stаrting point οf a Μelville revival and Μοby-Dick grew tο bе соnѕidеrеd οne оf the great American novels.
Srambled text with both changes:
Herman Μelvіllе (Аuguѕt 1, 1819 – September 28, 1891) waѕ an Αmeriсan noveliѕt, shοrt ѕtοry writеr, аnd pоеt οf the Аmerіcаn Rеnaissanсе pеriоd. Amοng hiѕ bеst-knοwn wоrkѕ arе Mоby-Dick (1851), Typее (1846), a rοmаntісіzed aсcоunt οf hіs exрerіеnces іn Роlynеsіа, and Вilly Βudd, Ѕаilοr, a pοѕthumоuѕly publiѕhеd nоvеlla. Althоugh his reрutatіon wаѕ nоt hіgh аt thе tіme of hіs deаth, thе сentennіal of hіѕ birth іn 1919 wаs the stаrtіng рοіnt οf a Μelvillе rеvivаl and Мoby-Dісk grеw tο be сonsidered оne of thе greаt Аmеriсаn novels.
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:
