Cyrillify obfuscates your text with Cyrillic homoglyphs. There are 15 uppercase and 7 lowercase identical homoglyphs shared between English and Cyrillic character sets. Each character in each pair has a distinct and unrelated ASCII code from its homoglyphic counterpart, yet an identical character manifestation across most regular font weights and types. Swapping out English characters with their Cyrillic equivalents has the benefit of obfuscating text, cloaking the content of pages from scrapers and bots while allowing humans to read content as normal.
var cyrillify = require('cyrillify');
console.log(cyrillify('U.N. Environment Envoy Quits After Audit of Expenses'));Output should look identical.
U.N. Environment Envoy Quits After Audit of Expenses
-- But instead of being: "U.N. Environment Envoy Quits After Audit of Expenses"
-- Punycode will be: "U.N.xn-- nvirnmnt nv quits ftr udit f nss-uh0ae0ngdmkac66ajat9grf9e"
console.log(cyrillify('[email protected], [email protected], [email protected], [email protected], [email protected]'));Output should look identical.
-- But instead of being: "[email protected], [email protected], [email protected], [email protected], [email protected]"
-- Punycode will be: "[email protected], [email protected], [email protected], [email protected], [email protected]"
console.log(cyrillify('Methanol was administered to rats, rhesus monkeys, and pigtail monkeys. Of these animals, only the pigtail monkey reliably developed a severe metabolic organic acidosis resembling that observed in humans.'));Output should look identical.
Methanol was administered to rats, rhesus monkeys, and pigtail monkeys. Of these animals, only the pigtail monkey reliably developed a severe metabolic organic acidosis resembling that observed in humans.

Cyrillify obfuscates your text with Cyrillic homoglyphs. There are 15 uppercase and 7 lowercase identical homoglyphs shared between English and Cyrillic character sets. Each character in each pair has a distinct and unrelated ASCII code from its homoglyphic counterpart, yet an identical character manifestation across most regular font weights and types.
Cyrillify's output will appear identical to its input, however, the code used to represent it will be different. We can verify Cyrillify's work in two ways:
Punycode is a representation of Unicode with ASCII. It is the encoding system used in encoding internationalized domain names. We can verify Cyrillify's work by using any of the widely available Punycode converters, checking the associated Punycode of the output to ensure that it differs from the input (see examples below).
The quickest way to verify Cyrillify's work via regex is to hit Ctrl+F on Windows, or Command+F on Mac, and search some of the Cyrillified content to see if the computer can identify it.
Swapping English characters with their Cyrillic equivalents has the benefit of obfuscating text, cloaking the content of pages from scrapers and bots while allowing humans to read content as normal. This is particularly useful in shrouding email addresses from bots without compromising their visibility in the browser from humans.
In the event that you are posting and Cyrillifying 'spun' articles, search engine web crawlers such as Googlebot, Bingbot, etc., will not identify the duplicate content, hence, will not penalize nor demote your SERP ranking. Cyrillify can therefore be used as both a weapon and a shield. Behave yourself!
With npm do
$ npm install cyrillify(MIT)
