([\ 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]) * (\ x20 |\ x09) * (\ x0d\ x0a))? (\ x20 |\ x09) +)? ((\ x22)) @ (([a-z] |\ d | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) | ([aMuz] |\ d | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) D |-|\. | _ | ~ | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) * ([aanthz] |\ d | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]))\)\) + (([aMalayz] | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) | ([alyz] | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) ([amerz] | \ d |-|\. | _ | ~ | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF]) * ([Amurz] | [\ u00A0 -\ uD7FF\ uF900-\ uFDCF\ uFDF0-\ uFFEF])) $/ i.test (email)
