Intl.Collator loose comparison of diacritics with str.startsWith()

compare.js

// probably not necessary to normalize, but let's cover our bets
var value = val.normalize()
var conjugation = this.conjugation.normalize()

// collator to do a loose comparison of characters. some characters like ț in Romanian
// have three or more versions, so this seems to resolve the issue
var collator = new Intl.Collator('ro', { sensitivity: 'base' })

// do the comparison, for feedback while they type
if (collator.compare(value.substring(0, value.length), conjugation.substring(0, value.length)) === 0) {

// we have a loose collator match, so we can mark this input as correct and finished
if (collator.compare(value, conjugation) === 0) {
  this.status = 'correct'

  // update store for this verb tense
