I can found a good regex for utf8 user email checking and quoted user email checking you can try these.

const emailUserUtf8Part = /^(?!\d)(?!...)[a-z\d!#$&'+-/=?^_`{|}~%.\u00A1-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]+$/iu;

const quotedEmailUserUtf8 = /^([\s\x01-\x08\x0b\x0c\x0e-\x1f\x7f\x21\x23-\x5b\x5d-\x7e\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]|(\[\x01-\x09\x0b\x0c\x0d-\x7f\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))*$/iu;
