Regexify dot issue

[IonBazan]

Summary

regexify does not handle [.] properly. It should treat it as literal ., not "any character" when it is in square brackets. This can be reproduced with test:

Faker/test/Faker/Provider/BaseTest.php

Lines 319 to 322 in 7dea0d7

	public function testRegexifyBasicFeatures($input, $output, $message)
	{
	self::assertEquals($output, BaseProvider::regexify($input), $message);
	}

using following data set:

Faker/test/Faker/Provider/BaseTest.php

Line 340 in 7dea0d7

['[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}', 'complex regex']

without seeding the generator (to assure randomness).

Versions

Self-enclosed code snippet for reproduction

<?php
$regex = '/[.]/';
$result = \Faker\Provider\Base::regexify($regex);
var_dump(preg_match($regex, $result));

Expected output

int(1); // result should match the regex

Actual output

int(0); // result does not match the regex
