Is there an option like /i to configure the regex so it ignores the

In general it could by done easily with some help of Lodash library, when you're testing two types of the same regex input - one is deburred by lodash _deburr function other is raw user's input. Example for username input form based filtering (with little help of lodash _filter function):

import _ from 'lodash'

const input = inputFromYourFormInput
const users = ['Jiřina Žlutá', 'Aleš Úzký'];
const regex = new RegExp(input, 'gi');

const filtered = _.filter(users, (u) => {
  const debured = _.deburr(u)
  if (u.name.match(regex) || debured.match(regex))
    return u
})

In this case It doesn't matter if your input is Jirina Zluta or Jiřina Žlutá _filter function will return new filtered array [Jiřina Žlutá]
