	if (extension_loaded('intl')) {
	return (idn_to_ascii($email, 0, INTL_IDNA_VARIANT_UTS46) ?: $email);
	}

Need to check if constant available ?

Duplicate of #192

In addition to my explanation there: If more people experience this, I think a check might be needed. Although I'm concerned about the state of their server OS if they depend on system libraries from before 2012.

@xtreamwayz I've created PR #194 for its check

We use Amazon, and the latest version of ICU library, (in accordance with #192) But it does not work!

Version: 50.1.2
Release Date: 2012-12-17
API Changes since ICU4C 49
Readme
This is a maintenance release affecting only the Layout Engine ABI. It only incorporates bug #9826 which fixes a regression in ICU4C 50.1.1.
Users not using the Layout Engine may remain on ICU4C 50.1.1 (see below for 50.1.1 changes)

@ArtemChornovol for workaround, downgrade set in composer "zendframework/zend-validator": "~2.9.2" is the way while waiting for #194 going to be merged or any other solution found for it.
