idna-normalize

Developed by blurpesec of MyCrypto for use on classification of homograph attacks tracked by https://etherscamdb.info.

To run:
const IDNANormalizer = require('idna-normalize')

const domainnormalize = new IDNANormalizer()

const normalizeddomain = domainnormalize.normalize('mycrỵpto.com')
console.log(normalizeddomain)
/* 
	Output is a string of the same length as the input string. 
	Only pass in idna strings. 
	If the IDNA character does not resemble an ASCII character,  it is left in the string.
