Input type email value in Chrome with accented characters wrong

For others who face this problem again, I suggest use punycode npm package. https://www.npmjs.com/package/punycode

I think only Chrome encodes email into punycode. There is no way to prevent Chrome from punycoding. You just let her do her work and decode punycode in backend.

const punycode = require('punycode')
let data = request.only(['email'])
data['email'] = punycode.toUnicode(data['email'])

Worked like charm in adonis and my headache disappeared.

I think it's not an error, it's because of the specification. Chrome just follows the specification in a different way than other browsers:) and translate the IDN into its ascii representation.

To decode it back you can use some 3rd party solution such as

Converting punycode with dash character to Unicode
