Summary

In some cases, like [a-z\-]{4} the slash in regex should be ignored. At least if we want to simulate php behavior. Currently, slash considered a valid character and «presents» in generated strings.

Self-enclosed code snippet for reproduction

for ($i = 0; $i<100; $i++) { 
    $v = \Faker\Factory::create()->regexify('[a-z\-]{4}'); 
    if (strlen($v) < 4) { 
        var_dump($v); 
    }
}

Expected output

Actual output

It fails in 7-10% of iteration in my setup. Producing output like

...
string(3) "srb"
string(3) "ncs"
...
